The following list shows how many of the downloaded pages contain posts from that account. The first 4 are real posts that haven't been deleted (they are in all downloaded pages), the 36 accounts after that are bumpbots (they post and delete their spam). There is a very small chance on of them was a user who really posted something and deleted it again, but that's very unlikely.
Mods: am I trusted enough for you to nuke those accounts if I provide lists like this, without further evidence? If so, I'll process other threads too. I'm curious to see how quickly the next batch of bots starts spamming after these are nuked. If bumpbots can be nuked fast enough, the spammers' business model becomes worthless. That leaves them spamming without deleting posts though, but that's something for another topic.
