This is not related to Academia at all, however, I've noticed that in the past week or so, numerous questions pop up that are spam. I flagged around 30 of them so far (or more) but they keep popping up in the Questions section, shadowing proper questions users have that are indeed related to Academia. Is there a way to solve this problem?
This is a consequence of the moderation strike, and of the community-built and community-run spam detection tool SmokeDetector having shut down as part of the strike. To quote from @cocomac on the main meta:
We have extremely good community spam protection. Or, we used to. Normally, there’s a number of tools used to fight spam and get it flagged very quickly 24/7. This means most spam gets deleted extremely quickly.
A number of users (myself included) object to recent actions by SE and are now on strike. As such, when the subset of the community dedicated to fighting spam stops fighting spam, there will be more spam visible. That is ... kinda the point. People notice when less moderation means more garbage (spam). Notably, the strike includes the primary system used for spam fighting.
The question of whether StackExchange itself should improve its own anti-spam system was raised here. In the meantime, users can either flag the spam posts, or leave them alone and hope the presence of spam serves as motivation for StackExchange to proceed with negotiations. Some progress has been made.
I would also suggest users refrain from editing out the spam in spam posts. This is not particularly productive, and can even slow down future conscientious flaggers; see Should spam posts be edited? for more details.
