Although i don't exactly agree with your proposal regarding the "confirm email" "problem", i do think that the forum can definitely improve on a number of things, and is HEAVILY lacking on certain features in comparison to other forums.
Its your fault that you didn't checked your inbox and lock your account at time.
Its your fault to not having the passwords secured.
Its your fault that not logging in for too long time.
Don't blame anyone because its your fault.
First of all provide link to your hacked account,then only someone can check the account is hacked or not.And also you can punish the hacked account by letting him a negative trust until your recover your account by sign in a message from the bitcoin address used.
Blablabla, the matter of fact here is simply that the forum's methods are heavily outdated. Other services would either never allow this to happen in the first place, or quickly recover the stolen account. Bitcointalk does neither.
Sure it was his fault, but do you seriously expect everyone to browse bitcointalk from an air-tight pc in some nuclear bunker? It's a forum for christs sake. There'll always be people/accounts getting hacked for various reasons.
