Is it really wrong to have picks asking people to read your article or to answer your question?

Ever since I joined Fanpop a few months ago I have heard about rules of some sort and I was wondering how people know what is taboo and what isn't. Which goes along with my question because I have read articles supporting these kinds of picks, but I recently have a read an article that states it is against "the rules". I would really like to get clarification on this matter and if possible the actual list of taboo things. Thanks in advance for help and sorry this is so long.
