You might have noticed we have a bit of a spam wave going on at the moment. The mods are getting it cleaned up. Thank you for all of your work flagging!
Please keep in mind, with spam users, the best thing you can do is flag as spam. You don't need to do a custom flag to send the mods a message - that actually slows the process down. As more and more spam flags come in, posts will be auto-deleted, and ultimately we can get the users' IPs blocked. We can also see the users who are drawing a lot of flags and nuke them, even if their posts have already been auto-deleted.
This wave is a bit unusual in using answers and comments to spam, which I at least haven't seen before. If you see comment spam, you don't need to flag that in addition to a question or answer post from the same user. It will get wiped out when we destroy the user's account. If you do see comment spam hang around, though, go ahead and flag to make sure it does not get missed.
Thanks for helping us keep spammers out and signal-to-noise high!
Edit with further notes: the spammers aren't using consistent IPs, but their patterns are now being detected by Charcoal anti-spam. This seems to result in most spam posts being hit with enough flags to remove them in less than 10 minutes. We'll continue to clean up where needed and destroy users to get them fed into Stack Exchange's own anti-spam system.
