It's going to be a Achilles heel for Wikipedia one day, mark my words. Those LTA pages often contains a lot of personal information which would violate GDPR in Europe, at least based on what I've heard from NOYB so far. Some editors have expressed their concerns about this.

On Wikipedia, every edit can be hidden so that even admins can't access it.[1]

Therefore, if legal problems arise with these pages, they probably will just delete the legally problematic info and hide every edit done before.
