Hello,
I successfully run discourse and now I’d like to disable logging users’ IP address.
There are many discussion of it as part of EU GDPR(2018, 2019), but I could not find the concrete solution for it.
You need ip addresses to fight abuse, so I think that most people have decided that the way that Discourse manages up addresses is not in violation of gdpr. I think that no plugin emerged to do what you ask.
A simple solution is to use an external reverse proxy and don’t configure discourse to use the reverse proxy ip address (which happens by default).
