I don't think that it's a sob story at all. I think that it's (a) incredibly funny that they would make such a mistake, (b) a combination of bad UI and bad service on Meta's part, and (c) crazy that even three Meta employees cannot undo such a ban.
So yes: It was my fault that I didn't notice or care faster. And sure, you can call this a sob story. But I think that beyond my personal experience and issues here, this points to some deeper problems with Meta, as well as other large companies that depend on AI.
