Please do not add inappropriate external links to Wikipedia, as you did to Ophthalmology. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include, but are not limited to, links to personal websites, links to websites with which you are affiliated (whether as a link in article text, or a citation in an article), and links that attract visitors to a website or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the page, please discuss it on the associated talk page rather than re-adding it.  MrOllie (talk) 12:07, 12 August 2021 (UTC)

Please stop your disruptive editing. If you continue to add promotional or advertising material to Wikipedia, as you did at Pharmaceutical industry, you may be blocked from editing. —Bruce1eetalk 11:04, 14 September 2021 (UTC)

 Your account has been blocked indefinitely from editing because of the following problems: the account has been used for advertising or promotion, which is contrary to the purpose of Wikipedia, and your username indicates that the account represents a business, organisation, group, or web site, which is against the username policy.

You may request a change of name and unblock if you intend to make useful contributions other than promoting your business or organization. To do this, first search Special:CentralAuth for available usernames that comply with the username policy. Once you have found an acceptable username, post the text at the bottom of your talk page. Replace the text "Your proposed new username" with your new username and replace the text "Your reason here" with your reasons to be unblocked. In your reasons, you must:
 * Disclose any compensation you may receive for your contributions in accordance with the Paid-contribution disclosure requirement.
 * Convince us that you understand the reason for your block and that you will not repeat the kind of edits for which you were blocked.
 * Describe in general terms the contributions that you intend to make if you are unblocked.

Appeals: If, after reviewing the guide to appealing blocks, you believe this block was made in error, you may appeal it by adding the text at the bottom of your talk page. Replace the text "Your reason here" with the reasons you believe the block was an error, and publish the page. Justlettersandnumbers (talk) 11:24, 6 November 2021 (UTC)
