I wish there was an official guide on how to run a forum properly, because all forums suffer from the same problems. What I figured out so far: You as a forum administrator must delete that personal data on request. This could mean digging through all posts of a user and delete all PII, although you don’t have to delete all posts if they contain no PII. You as a forum administrator must get your privacy policy right and possibly make it harder for third parties to index PII. This depends on your intentions and whether or not people know that your forum is public. Say, your forum is about car parts. You could set a subforum that asks members to introduce themselves (where PII are most likely) to noindex or hide from the public. This way, you’ve put in reasonable effort to protect your users and your obligation is done. Indexing by third parties is now out of your control. But say you run a medical forum where people post health data (considered super sensitive) and are expected to post a lot of PII, you might have to set the entire board to ”members only“. Although I’m not sure about any of this and to some extend, most forums provide value by being visible to visitors and indexes by Google. Quite sad.
