I've just seen this in the offtopic section, is it allowed, can I spam the forum like that or only the hero members can?
Just asking...

You should check his posts then before replying.
Posting so much in off topic in any case should be considered spam, because of the time-frame. The time between some posts is less than 30 seconds (!).
All the posts consist out of a few words. I could be wrong here.
A person that is participating in a sig. campaign would be banned if he posted like that.
