I don’t know if we would be reposting really old posts or not so I’m not sure if that would be an issue. I think the opt out system is a good idea. At least it gives the creator a chance to decline the repost. Especially if we give them a decently long enough timeline to respond.
I wonder how this would all be enforced. Would you need to screenshot your PM to the OP?
Took me a while to figure this out too. I’m using the Memmy app.
