Basnayaka has been using Karalikaraya to carry out problematic edits:
 * List of research universities in Sri Lanka - Basnayaka was editing this article between 8.00 and 8.12 on 24 October, then logged in as Karalikaraya to remove an Afd between 8.23 and 8.38 on 24 October.
 * South Asian Institute of Technology and Medicine - Basnayaka removed the article from Category:Schools of medicine in Sri Lanka without any explanation. This was reverted by another editor but Karalikaraya then removed the category once again.

The accounts are editing similar articles, sometimes even adding/removing similar content:
 * List of universities in Sri Lanka - Basnayaka v Karalikaraya.
 * South Asian Institute of Technology and Medicine - Basnayaka v Karalikaraya.
 * National Academy of Sciences of Sri Lanka - Basnayaka v Samanalaya1.
 * Education in Sri Lanka - Basnayaka, Karalikaraya.
 * List of research universities in Sri Lanka - Basnayaka, Karalikaraya.
 * Sri Lanka Institute of Information Technology - Basnayaka, Karalikaraya.
 * University of Ruhuna - Basnayaka, Karalikaraya.
 * Sri Lanka Institute of Advanced Technological Education - Basnayaka, Karalikaraya.
 * Inter University Students' Federation - Basnayaka, Karalikaraya.

The times the accounts are editing very close to each other but do not overlap suggesting that they are under the control of one individual:
 * 29 May 2016: Basnayaka was editing between 6.12 and 6.27 and then Karalikaraya was editing between 6.41 and 6.45.
 * 1 June 2016: Karalikaraya was editing at 19.51 and then Basnayaka was editing between 19.59 and 21.10.
 * 26 August 2016: Karalikaraya was editing between 15.19 and 16.01, then Basnayaka was editing between 16.23 and 16.27 and then Karalikaraya was editing between 17.15 and 18.35.
 * 21 September 2016: Basnayaka was editing between 19.37 and 20.12 and then Karalikaraya was editing between 20.28 and 20.54.
 * 25 October 2016: Karalikaraya was editing between 6.51 and 6.53 and then Basnayaka was editing at 6.59.
 * 25 October 2016: Karalikaraya was editing between 18.53 and 19.18 and then Samanalaya1 was editing at 19.33.
 * 27 October 2016: Basnayaka was editing between 12.16 and 12.19 then Samanalaya1 was editing at 12.42 and then Basnayaka was editing between 12.56 and 12.57.  obi2canibe talk contr 16:55, 29 October 2016 (UTC)

Previous investigations have established that Basnyaka is the sockmaster of Karalikaraya, Samanalaya1 and Siyaladath all of which accounts have been blocked. On 13 May 2017 Samankamal performed his first edit by removing the content on List_of_universities_in_Sri_Lanka releated to colleges and Insitutions, this similiar to Basnayaka v Karalikaraya.

The accounts are editing similar articles
 * South Asian Institute of Technology and Medicine - Basnayaka v Samankamal.
 * Education in Sri Lanka - Basnayaka, Samankamal.
 * Sri Lanka Institute of Information Technology - Basnayaka, Samankamal.
 * University of Ruhuna - Basnayaka, Samankamal.

The user has been constantly removing or changing content related to South Asian Institute of Technology and Medicine medical degree program, Basnayaka v Samankamal

Basnayaka has been emphatic in asserting that South Asian Institute of Technology and Medicine medical degree program is not recognized by the SLMC Basnayaka, user Samankamal similarly adds content to the same effect  Samankamal

Additionally, user Samankaml has a smiliar name to user samanalaya1, whose was established a sockpuppet of Basnyake in a previous sockpuppet investigation. -- Eng. M.Bandara -Talk  08:03, 18 September 2017 (UTC)

Reltionship between 192.248.50.253 and Samankamal

 * - There quite a few edits from the IP, across multiple articles and spanning several months, that appear to be part of blocks of edits from the master account. See for instance Damascus steel (1 January 2016), Information Technology in Sri Lanka (19 October 2016), Lanka Education and Research Network (23 October 2016), List of universities in Sri Lanka (1 May 2016). This happens a little too frequently to be a coincidence. The common position of the IP and Samankamal in the edit war at South Asian Institute of Technology and Medicine presented above shows a pretty clear link between these two as well. As such, I can only conclude that all of this is one person. Please block the named account indefinitely. Given that the IP has edited consistently since at least May 2015, please block it from an extended period of time. Sir Sputnik (talk) 16:32, 22 October 2017 (UTC)

was blocked in September 2017 as a sockpuppet of Basnayaka. A new user account has appeared which is making similar edits as Samankamal:
 * NSBM Green University: Samankamal v SLwriter
 * Inter University Students' Federation: Samankamal v SLwriter

Both accounts also are also questioning the legitimacy of South Asian Institute of Technology and Medicine:

 * Active in the exact same range of pages targeted by previous socks of Basnayaka which include,
 * National School of Business Management
 * Sri Lanka Institute of Information Technology
 * List of universities in Sri Lanka
 * University of Ruhuna
 * Inter University Students' Federation


 * Editing pattern is exactly the same
 * For example in the SLIIT page Samankamal has 1,2 ,3 ,4 while Chathu69 made 1, 2,
 * In the NSBM page: Samnkamal, SLwriter, 1, 2 and Chathu69
 * Another account Chathuwr is similar in name and the range of edits are largely within that of Chathu69 for example in University Charter Chathuwr vs Chathu69. It is also used to add the same work as in Chathu69 vs Chathuwr. It is most likely used as a WP:SLEEPER.

The edits, summaries and the range of pages are identical to socks of Basnayaka - UmdP  09:18, 23 October 2021 (UTC)

Accounts also have a common obsession with replacing Private University" as "Degree Awarding Institute", engage in disruptive editing and battleground behaviour to push that specific view. Pretty sure its a WP:DUCK -  UmdP  10:44, 26 October 2021 (UTC)

I think User:UMDP is attempting to abuse Wikipedia's Sockpuppet investigations facility by claiming false accusation  with "bad faith." User:UMDP probably started this investigation because we have some disagreement on the following pages.

Chathu69 15:28, 27 October 2021 (UTC)
 * Talk:Sri Lanka Institute of Information Technology
 * Sri Lanka Institute of Information Technology
 * Science and technology in Sri Lanka
 * Talk:General Sir John Kotelawala Defence University
 * General Sir John Kotelawala Defence University
 * User talk:UMDP
 * Sri Lanka Technological Campus


 * You clearly lack the basic competency to edit Wikipedia as multiple editors like User:Obi2canibe and User:Cossde have clearly stated why your edits are reverted here and here and I have explained as well. However you engage in WP:TENDENTIOUS editing continually refusing to WP:LISTEN and when an account gets banned another comes and does the same thing again and again. - UmdP  16:29, 27 October 2021 (UTC)

 * Based on overlap in edits and general interest in adding negative content to several of these Sri Lankan universities (or not-universities, or whatever), I feel quite confident that Chathuwr == Chathu69 and reasonably confident that both are Basnayaka. . Most of the IPs are very dynamic and most are stale, don't think there is any value in blocking them. GeneralNotability (talk) 23:51, 5 November 2021 (UTC)

Persistently edit warring an article over a redirect on Age of Information. Behavior is very persistent. Jalen Folf  (talk)  04:44, 11 November 2021 (UTC)

The sockmaster is using different IPs to harass me for catching him and taking down his citespam. I think its best to put him in the long term abuse list because he isn't going to stop as shown here 43.250.241.6 and 61.245.171.110 - UmdP  14:16, 12 November 2021 (UTC)

Basnayaka has shifted IP range to 2407:C00:0:0:0:0:0:0/32 using 2407:c00:e005:1898:2c28:13ec:62cf:2de8 to restore citespam and using 2407:c00:d001:2b3c:2c28:13ec:62cf:2de8 to restore general content of previous socks. - UmdP  19:32, 13 November 2021 (UTC)

 * As to the initial cause of this filing, : There's been no disruption at the redirect for 10 days, but the history shows they have a long memory, so please semi-protect  for a year. The redirect, that is, not its target. (On that note, check out noredirect / -r for linking to redirects.)As to the rest,  I'm sorry that you're dealing with this harassment. I'm afraid that there isn't much SPI can do here, though. The IPs are just too dynamic, with too much collateral on the range for a rangeblock and too broad an array of targets for a pblock. This sort of quick-moving abuse is best handled with page protections and timely reports to AIV and/or the admins of your choice.  --  Tamzin  [ cetacean needed ] (she/they) 05:13, 22 November 2021 (UTC)

Same IPs and similar IP ranges used previously by Basnayaka/Chathu69 suddenly activating to reinsert edits carried out by Basnayaka/Chathu69 socks which is obvious ban evasion. Eg- Chathu69 vs 43.250.243.191 vs 192.248.81.93 212.104.236.42 also edited the same range of articles targeted by Chathu/Basnayaka socks alongside the other IP socks within the exact same period. 192.248.81.93 has been consistently used by the same person so its probably a static IP and could be banned permanently. For others I think temporary range blocks will be needed again. - UtoD  14:17, 17 January 2022 (UTC)

The specific edit being pushed has already been reverted and has been reverted in the past. The IPs and ranges of the IPs used have been previous used by the same user that made the same edit previously. Its fair to say there is a ban evasion here. - UtoD 16:07, 25 January 2022 (UTC)

 * - Can you be more specific about which edits are disruptive? From what I can see, virtually all of the edits by these IPs remain unreverted, so I assume people didn't find them a problem. -- RoySmith (talk) 14:37, 24 January 2022 (UTC)
 * At this point, the IPs haven't edited for a week or more, so blocking isn't going to be useful. I semi-protected the most common pages they've been editing.  As a practical matter, WP:RFPP is almost always faster to respond than WP:SPI, so that's probably a better place to go for stuff like this. -- RoySmith (talk) 14:17, 26 January 2022 (UTC)
