You agree to not use the Service to submit or link to any Content which is defamatory, abusive, hateful, threatening, spam or spam-like, likely to offend, contains adult or objectionable content, contains personal information of others, risks copyright infringement, encourages unlawful activity, or otherwise violates any laws.
If you feel that you are being personally abused or picked on Matth, then you could try to report it to the owners using the offending comment as evidence, but I wouldn't hold your breath.
Personally, I think anyone that bullies a person that quite clearly does not have the social tools to defend themself properly is a bit of a coward.
