I'm not sure what people would be trying to access, I suppose. Post history? Things that can be exported, like account settings, generally should be stashed somewhere. Things that can't be, well... That's a bit sad but I dunno, I never post anything online that I care so much about I'd be sad if it disappeared. Anything I did care about, I make a backup of it locally.

Not trying to downplay people's upset, but just pointing out ways to protect the things you care about.
