I can understand deleting entire threads where discussion of illegal activity or violations of user right to be forgotten is occurring, however using deleting whole threads (not just singular posts) in places where the violations are more minor can lead to confusion amongst users, and uncertainty regarding moderator action.
For the “right to be forgotten” This phrase is from the GDPR and the GDPR has a pretty clear definition what falls under personal information and what not.
And all posts where I was lurking or active and got deleted were not violating the GDPR.
Besides the fact that the talking about deleted users in this post didn’t fall under personal information, it should be also mentioned that the right to be forgotten doesn’t apply if right of freedom of expression and information is suppressed.
So this whole “violations of user right to be forgotten” is merely a complete nonsense.
