[J a v e l j a]

look on google for an addon that does that, best way here on warmane i have found for the goldseller spammers is to take a screenshot and upload it to
http://imgur.com/ then copy the link and send it to aldtharios with the name of the spammer, and your reason for reporting him. the spammer will be taken care of :)

The most well-known AddOn for things like that would be BadBoy.

Also take a look at its plugins:
BadBoy_CCleaner - filters based on certain words/strings
BadBoy_Guilded - filters and blocks guild adverts


Another one is SpamMeNot.
