We appear to be under a sustained attack by spammers. I am deleting them in batches as they accumulate. I apologize for the thread clutter, as well as for the PM spam. There is also no need to report spam threads in the spam reporting thread; I see them.
One of the spammers posted a "normal" test post to the Off-Topic board in response to my sticky post about not making Off-Topic your first post. This shows we have a human being who can read and react who is hitting the board, and that this isn't just an automated bot that found us and is spidering us for a while.
I have reached out to TheoW, and presumably he will be contemplating what we can do to harden the board against further incidents.
