According to some images, Twitter low level employees can see email address of all accounts (and I guess phone numbers). I know some celebrities have their real email address and phone numbers on those accounts. Isn't that something bad?
Perhaps a higher tier of user support personnel handles verified accounts (or accounts somehow flagged for extra review in a non-public fashion), but I'd still be surprised if anyone particularly high-level is doing the grunt work of using this tool.
I imagine a support person does more than in an average day.
And while we might have seen all the tweets at the same time, they might have been changing emails and passwords over few hours.
Remember twitter has so many users they probably get tens of thousands support requests per day.
Even if you have monitoring, I don't think volume was enough to pick it up.
Although I could be wrong if the reports are wrong too.
