We value any contribution to the forum, even in languages other than English. However, spammers have been not only a recurring, but an increasing problem.
To everyone whose post has been rejected/disapproved, please consider posting in the off-topic area before having made any substantial contribution (including meaningful questions) in the on-topic fora. If you feel your post was removed wrongly, feel free to contact us. We are human, too. We make mistakes, sure. But if your post basically is off-topic or simply a remark there is a chance that it gets disapproved.
We have seen many a tactic used by spammers to sneak their links into the forum. It seems to be the burden when having a certain page rank. Oh well.
I just implemented some more antispam features and more are to follow without notice.
My plan includes the implementation of some heuristics to find spammers after the fact. Often they come back to edit their signatures or posts and include spam links. Heuristics will be able to help us find existing spam and refine our means of detecting it as we go.
