I have been posting relevant links in Wikipedia which keep getting removed. I got a message from the moderator who keeps removing it. He said that next time I will get black listed from search engines. Can Wikipedia blacklist my site ?
Hrmm Black Listed because of a Wiki Pedia posting? It depends really, on the content of the page you were posting on but no the moderator himself of Wiki Pedia doesn't have the power to black list you.
Wikipedia and Google have no affiliation with each other. Therefore, wikipedia can not block you from the Search Engines. One of your competitor could be trying to get your site banned. Also, wikipedia uses nofollow tags as with Youtube does too.
If that's true then everyone will post their competitors websites on wikipedia to get some competition out from the serps The next time the wiki guy says anything like that, just tell him that its not your site, its your enemies/competitors site, so get it banned And a small suggestion, post links in the external links section of the wikipedia article, and make sure that your site is non-commercial, because wiki pedia don't accept commercial sites.
