Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, we would ask that you assume good faith while interacting with other editors, which you did not on Talk:Yadav. Take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you. Accusing other editors of "trying to defame the Yadav Clan" constitutes a Personal Attack, and will not be tolerated. There are discretionary sanctions applicable to caste articles, and I will provide you with details shortly - but if you make further accusations against other editors, you should expect to be blocked from editing -- Boing! said Zebedee (talk) 16:08, 11 October 2012 (UTC)[reply]
The Wikipedia community has permitted administrators to impose discretionary sanctions on any editor who is active on any page about social groups, explicitly including caste associations and political parties, related to India, Pakistan, Sri Lanka, Bangladesh and Nepal. Discretionary sanctions can be used against an editor who repeatedly or seriously fails to adhere to the purpose of Wikipedia, any expected standards of behavior, or any normal editorial process. If you engage in further inappropriate behavior in this area, you may be placed under sanctions, which can include blocks, a revert limitation, or an article ban. The discussion leading to the imposition of these sanctions can be read here.
