I've now got back to the 24th October 2023, marking all the spam on the way. That involved marking some stuff that I'm pretty sure that I'd marked on previous passes, so it may need to be repeated more than once.
The flood did seems to start the 24th October, and there were quite a lot of call girls, fake drivers licenses, fake term papers, psychodelics and pharmaceuticals in the mix - it wasn't all on=line gambling.
