I have been increasingly having to re-run my purge scripts across multiple accounts, despite not being on reddit for a few weeks now. The longer i wait between logging in and purging comments, the more appear.
And they do appear quasi-random, as if they page/comments get restored when another user pulls/visits an older page.
How does this even square with privacy regulations anyhow. If a user wants to delete their comments, forcibly restoring them against their will is, at best, unseemly.
I don’t think you can edit/view comments from privated communities, could it be that as subs are being forced back open those comments are now available to be edited.
