Looks like Hubski has grown enough to attract the attention of spammers who go beyond basic linking. In case of linkspam ignoring them usually was enough, but ignoring, muting and hushing the comment spammers doesn't hide their posts.
Self promotion should be acceptable as long as it is relevant and contributes, posting the exact same comment on topics tagged #bitcoin, no matter how relevant the comment is to the post, shouldn't be.
As Hubski grows, this will only get worse, and current self moderation options don't go far enough, especially in topics without many comments.
Maybe a "report spammer" button to take care of these?
