Yeah numbers don't seem to have dropped much looking at the memberlist - about 50% not activated as it has been a while now, and pages of blatant bot accounts. A lot of the time it seems like there's a decent time gap between when they sign up and when they actually spam so it might be possible to reduce it a bit by patrolling the memberlist sorted by most recent signup for obvious bot accounts and banning them pre-emptively, but that takes a fair bit of time and effort.
Thing is for you and I (well, I'm *pretty* sure you're one of the other few people consistently on at this time of day), we see them a lot more than others because around this time there's a window where we usually don't have anyone online that can actually do something about them. It's not so bad, because usually a mod comes on near the time more people come online and as this is like the least active time period, only a few of us really notice it from what I can tell, but yeah, still annoying haha.
