For the record, deactivating your Gyrate account resets the password to something random, but it leaves the email address alone in case you might want to recover your account later. If you really want to disappear without a trace, you can just delete the email address yourself since it's an optional field.

I have an idea to protect against bots by building a web of trust (that's what invite-only mode and the invite system are for), and actually deleting the account record would mess up the user tree. But I also don't like having a bunch of garbage data in the database, so I'm not exactly sure how I want to deal with that yet.
