There's a pretty steady wave of spam attempts at the Wiki, but they are from bots that have been running fairly consistently for (literally) years now - every 2 minutes, the same set of pages get attempts with the same set of spam. Those I've had blocked for eons. What's interesting to me is the reduction in other spam.

Up until about a month ago, there were waves of spam that kept cresting, coming from different IP addresses, and with different payloads. I had to block those as they happened, and adapt the server to them. Then it pretty much just stopped, leaving the rump set of bots that I mentioned above.

I'm not sure why the waves stopped. I'm not complaining either, but something definitely changed.
