lol... go try hosting warez with them.http://webthosting.com allow it
By the time you do, they will either suspend your account for using too much space.
OR when you do, it's just a matter of time until you get caught and then get terminated =/
Just b/c they "allow" it, doesn't mean you won't get into trouble for it lolo
As for hosting a "huge" board.
You are probably better off getting a small VPS. high traffic boards are not good for shared hosting.
shared hosting is for small websites
