spammers / slow performance

Hello Bloggers, we had a massive registration / post spammer, and currently have a very poor performance - we're working on that issue and expect to be on full speed again within an hour! UPDATE 18:25 CET - everytime we block another email domain or some IPS the spammer just changes them, but we detected a pattern in what he does and are going to develop some automatic procedure against it, we're not so slow anymore but not yet fast again! thanks for your patience! Greetings from the Team!
