looking at your post history I see that you make a lot of very short posts, they probably are what I would call "two liners" (that is a little bit longer then a one liner but still very short). Although, after looking at your post history, it looks like your posts since what was most likely your last ban were actually one liners.

Prior to your last ban you also seem to have been using the 'return' key in order to make short posts look longer then they really are by creating a new line after only ~1/3 of a line.

I would suggest putting more effort into your posts.
