I think there should be a Forum Games/Spamming subforum that doesn't increase anyone's postcount for all of the forum games threads to be moved into.
This needs to happen, the game topics are a little out of hand. Post count spam, one word replies etc.
Or in a more simple way, forum count can be removed. Just titles stays (although they could be removed for non-moderators / non-pixel artist. One good functioning model is forum with no post count and no such titles... Just moderator can give personalised titles as a reward to the users positivly active on the board. It kinda makes flood be useless and, ikn addition, force the "titles hunter" to be respectful and involved in a positive way in the community).
About the animated avatar / signature, I think it's pointless to punish it right away, although it's really annoying. Maybe a word on it in the avatar page and a first warning before punishing can be sufficient.
I wouldn't also be really picky on the grammar. This board is quite internationnal and, from what it seems, there is only a few native english speakers. Mine for instance is really flawed. in the other hand, I suppose "sum kind a int3rn3t sp34k kan b littl annoying 'kuz make sing hord 2 understan' ". Here too there is maybe something to write about, as mus as the abuse of smileys and CAPSLOCK§
Back on the toppic flood, there is also some behaviours which are annoying such as double / triple posts. Maybe reminding that there is a "edit" button is not a bad thing.
EDIT : And congrats orci for your promotion :)
