How about blocking bigotry and hatred. Some neanderthal from North Carolina called charlie_foxtrot feels he has to post "I hate gay people"
Cancel memberships of people spreading hatred and bigotry.
FWIW I often leave the flame/hate comments in place when they appear on my videos, especially when the comment neatly exposes the person posting it as a stupid arsehole.
You can either add/remove a user from your Block List here: http://www.xtube.com/my_messages.php
It's for such reasons that I praise XTube for 2 features, of which one enables me to delete anothers comment from my page, & the other is to block a member from posting a comment on my page (I hope it also prevents this blocked member from also posting comments on my pic & vids.).
Thank you for bringing this to our attention. However, the user is not violating any Terms of Service.
