My understanding is that they log pretty much everything using Scribe and run analysis using Hadoop and Pig (based on a talk by Kevin Weil and NoSQL EU the other week) http://www.slideshare.net/kevinweil/nosql-at-twitter-nosql-e...

> They aren't able to keep a lot of logs due to the volume.

That's pretty much untrue.

Anyway, I don't imagine it's too hard to grep the logs for the last day's worth of POST and 'accept .*' and undo all the follows constructed from that.

They are at least able to tell if you've used it--my account just lost all its followers. http://twitter.com/sjwalter

I'd had a legitimate 30ish followers, used this bug a few times, now 0.

well, i can tell you right now that my followed and following lists were both just now wiped out, and using the accept bug now produces an internal server error.

edit: seems everyone is at 0/0, but the bug still produces an error for me.

Well, I just tweeted "accept failure" :-)
