What I don't get is the threads have like 40-50 views. I did go in and click the "report" button (the caution triangle) on some of them. If everyone else was doing that... surely the thread would auto-disappear after like 10 flags?
It's annoying that you can only report one of those each 60 seconds. For a couple times I would wait, and report both, then I felt like it was a time waste, so I did just one... now I do none.
I've been trying my best to delete them when I see the spam. I have admin powers, so does Piers. I have tried contacting the people in charge (autoguide) but they don't seem to be concerned. Most of the spam does seem to end up in Off Topic.
I just received a personal email from Ben Bradley, responding to my turning in one of those spammers. He says that he has had nothing to do with SS for over 2 years and that he has no access privileges any more.
Unfortunately, it'll be a losing battle if nobody has control of the site to update the captchas or something similar. Seeing the uptick just means that they've adopted a release which defeats the current stuff here, not much else can be done.
