+1 for email verification
-1 for manual mod reactivation, because it's too much of a hassle
-1 for the BTC address idea, because it links forum accounts to wallets, which may become corrupt, or lost. Not to mention the possible incompatibility with 3rd party clients.
I would say at the very worst, after an account hasn't been logged into in 3 months, reset it so that they need to do email activation to use the account again... But even that would be tricky to set up, and I think it should be an opt-in feature instead of default.
that kills the whole point. the purpose is to ensure ignorant users' accounts can't be used by scammers. Do you think ignorant users are going to opt-in to any feature?
How about locking satoshi's account too ?
We already have, but for unrelated reasons.
Are you afraid someone manages to hack into his account (0day exploit in SMF, gueesses pwd, whatevah) and impersonate him?
this actually happened. that's how the db got leaked.
