I'll be sure to note down the next time Bay12 goes down as "Retaliatory attack for an attack made by a user on Bay12 on a different forum." There's probably better phrasings for that; I'll have time.
I mean as I said it's unlikely they'll find it.
Yeah, Bay12 being at the ass-end of the Internet, it would be hard to figure out where we are. It's what's known is the business as "security through obscurity".
Plus, Bay12's huge. 4.8 million posts, 170 thousand topics, and 56 thousand users is no joke. Good luck trying to delete every single post, topic and user in time before Toady catches on and shuts the servers down. I vaguely remember that the last time Toady deleted a "big" (someone with a long history here) user's account along with every post of theirs, it took an hour or two. If they had 5000 posts, then it would take around 40 days and 40 nights of uninterrupted server activity to delete every single post.
So, you know, perfectly doable. Just need to incapacitate Toady and friends for 40 days straight to pull that feat off. I dunno if they have backups or not, but it probably exists somewhere. Not to mention everyone with an account elsewhere, if you don't wanna blow your cover.
Would such an attack qualify as a world record for "longest complete-destruction cyberattack on a single, independent (i.e. not Google, Amazon, Microsoft...) website"? Eh, I'd say just go for Gaia Online or something if you
really want that record. (No, I'm not endorsing that at all. Just saying it's a better candidate for the world record. We're nothing compared to that behemoth.)
