Well, I'm trying to do my best at wiping spam accounts as I see them
:) Userbase is not huge and usually there's only 1 or 2 new accounts
per day, so it's feasible to just have myself in registration_watchers

No, I have only list of gmail JIDs and I don't know if they also sent
any messages to gmail users. All gmail JIDs added by spam accounts was
different and I suspect that spammers scraped it somewhere and now are
just sharding it between spambots, but that's only my guess.
