Hi all! I run the forum at https://community.letsencrypt.org/, and have found Discourse to be a huge win over the years. Our forum is so critical to our success.
However, we’ve noticed a new pattern of spam. People will sign up and post comments that seem really legit, then hours later they will edit those comments to add links to sites they are trying to report. When we dig into these, it turns out the “legit” comments were copy-pasted from other threads, or from our GitHub issues page. If you’re Discourse staff, you can read our thread about it (note: It’s in our Lounge, so others won’t be able to see it). As far as I can tell, this form of spam appears to be driven by real humans.
I’m curious, has anyone else been seeing this form of spam? Any ideas about countermeasures, other than flagging? One member of my forum suggested it would be helpful to have a feed of posts that were edited after posting, or particularly posts that were edited to add links.
