yes, there is something that can be done about that. all that's required is a screen shot (or a few, to show more, how abusive it is), and then to send it in to the moderators via the correct channels. if you don't know how to take (and save) screenshots, just use the "search forum" feature, and it should come up fairly quickly.
then go to
http://www.flyordie.com/contact.html
and click "moderator contact form". fill in the info... a subject line like "reporting abuse" or something like that, and attach the file showing the abuse. give it a few days, and that person will likely receive a demerit or ban.
if they come back again and do the same thing a day or a few days later, just send in another screen shot. each time they get punished, it'll be for a slightly longer time. and if they show they're not going to stop, mods will eventually ban them permanently.
