Sorta a strange question but I'm trying to work with a hosting company usware.net where a website they host spammed our message board. well the user made 3 posts before i bannned him and moved the messages to a host only section. I kindly explained that a user was posting unsolicited ads for his/her site on our message board and becuase I moved the posts to a host only section i could not provide public links to the content so I took a screen shot of messages for proof. what do i get as a reply today? request for an email header!

I'm just looking to see what most hosts consider as spamming(unsolicited advertisement)? Is it just email or do you consider other forms such as usenet, bbs, message boards/forums, guestbooks, etc...
