Preventing spam? I can increase my post count just by 'flooding' -- I think that is the term. What this code does, if no one posts in the slot 2 or 3 and I take those spots, I got 3 posts automatically. What appending does is it takes all the posts from that one user and merges them together with a hr tag.
Example of fixing the flood:
Poster 1: (sauske)
Hi yall I made a post.
-------------------------------------------
Hi yall I just posted again cuz i likez 2 spam!
Example of another user posting:
Poster 1: (sauske)
Hi yall I made a post.
Poster 2: (Craizen)
Hi, I see you made a post.
Poster 3: (sauske)
Yeah, thanks for noticing!
Notice how there is no appendation? It would be fairly easy to implement. All you need to do is check the posts. If the post was made, and no one posted below, then merge the posts together!
