...a while back. (Not sure which thread)
Looks like they're active again on the original site...
Ex:

Might be taken down soon by the mod. There was another post on the main page that was also removed as spam from earlier.
I guess that answers if those bots are still around!
Edit: Looks like they deleted that message but the board been hammered a bit with more spam posts. I also noticed that the IBM mainframe mailing list I'm subscribed to also is getting spammed all of a sudden with messages. I hope I don't end up having to concoct some additional anti-spam filters here...
