all you have to do is tell the moderator with a link of the user, a link of the problem, and what the problem is. preferably a moderator thats on for a good response time.
I think you are the one he is trying to report because of the comments you posted on Naruto's page and you argued about it with him, so stop bothering people. Just try to ignore eachother, so we won't have any big arguments.
You can't block a user at the moment but I think AG might be working on that.And if you wnat to contact a mod all of them are listed here or if you prefer not anyone able to see your comment do it by the contact page!I am suprised no-one mentioned that.
