There might be another reason, but looking over the posts that you have made with that account, they aren't particularly constructive. Most are just a sentence which don't add to the discussion. It seems like you may of been doing this on purpose to boost your post count, because of the signature campaign you are involved in.

Of course that's my interpretation, and it could be another reason why you have been banned. But, I would say it was due to the quality & quantity of posts you were making.

Login, to your account and tell us what the exact message says, we can confirm whether it's permanent or temporary. Although, if this is your first ban/warning then it's likely the staff team gave you the benefit of the doubt and it's only a temporary ban. Looking at your posts though, it's likely you were warned way before this happened.
