Both the accounts and the IP address have edited exclusively in the last few days and only on the Shanghai Tower article. All three of them have made nearly identical additions to the article, promoting Jason holtzman's (same name as the user) website and claiming that his design for the WTC in New York had been copied by the designers of the Shanghai Tower.

Here is an example of nearly-identical content that has been added to Shanghai Tower by all three users:, , and finally.

After I reverted the first attempt to add this content by the IP user, he used the Jason holtzman account to try to add it again. After I reverted the second time and warned that account about self-promotion, he used the Qiantu account to do it a third time. Difference engine (talk) 17:54, 8 February 2015 (UTC)
