They must have increased the number of IPs they're (ab)using.
If the IPs are all in the same range, perhaps a limit on IDs created per appropriatelysized range per hour is the way to go.

Perhaps a solution would be to require that everyone register their ID and Email with the site. That would challenge the spammer a little more; at least make him work a little harder when using multiple IPs. You'd lose the anonymity that we have now. I would not be opposed to that.

Unless the new limits have been eased (which it doesn't sound like they have), I think the return of the spam puts to rest any idea that this spammer is a misguided, rather than malicious, individual, as some people here had posited/hoped. Markus should seriously consider contacting the police and/or a security consultant as the next step.

factordb loses me. I picked a number, a play on my dad's birthday, which is 8 digits and searched. It was there. On the farleft side was "FF" meaning fully factored. Behind the number I searched for were several small numbers. How can something be fully factored if the largest factor is three digits long?

The number I was goofing with is 18061923. ddmmyyyy. I expected a composite of this size to have a larger factor. Then again, maybe not. None of this is important. Just a curiosity.

The number of prime factors of a number n is on the order of log(log(n)). An 8 digit number can be tentatively expected to have 3 prime factors. So, a 3 digit prime as the largest factor is not that strange.
