It might just be that your posts are complete garbage. You seriously might want to consider that possibility.
OP take note of most of the advice given here. It's a tough forum to post on, because the standards are very high. As this dude ^^ alluded to, if your posts are crap, they will get deleted and you might risk getting banned as well.
Especially if you're in a signature campaign.
