We are hit by a massive spam wave for days now. Others like https://ask.learncbse.in/ gave up for the moment as it seems :thinking: I’m searching here just for one variant: [image] The content changes often, the email addresses and IPs as well so blocking does reduce the amount but we didn’t fin…

Have you tried adding certain words to Admin → Customize → Watched Words → Require Approval? From your screenshot, I’d try adding these words: cash credit money loan toll-free customer care care number 0779* helpline :point_left: It can be slightly inconvenient for users, but I have Discourse se…

Thanks for the hint but please check out https://ask.learncbse.in/ (it’s not my instance but the posts are more or less the same I’m fighting against) and scroll through the last days, they are using a ton of combinations and variations of each keyword.
