Perhaps, this page can help answer your question, provided this is a problem on the wiki network and an administrator isn't adequately handling the situation (or is the bully).

If it's for real-life, then there are also some other relevant links, but the best advice is the last dotpoint: seek an adult and consider options by the law.

Hope this helps.
