I just destroyed a spam / robot account that was just copying the help text into answers and posting them. The ID was 2045498.
Upon hitting 'destroy', I got the lolcat exception page. I loaded the user's profile again (following a link from one of the junk answers, not refreshing) and this is what I saw:
- The name had been de-normalized
- No traces of the 5 spam answers that previously existed
- No bio data at all
However the account still existed. Destroying it again worked. Bug, or perhaps something related to the testing / maintenance that's going on? It's almost like a transaction failed.
Noting it here in case it's the prior.
