If you are thinking about selling, I request you not to do it as the buyer may scam people.
Yes they can.
For me personally it depends on the reason of selling/buying. As long as people use it for signature campaigns I don't really mind. Sad enough the accounts are often used for scamming as well.
And often the people buying them get scammed as well, especially if they don't use escrow,
but also because they're easily recoverable by PMing theymos.I doubt that. My previous account got hacked during the bitcointalk.org hack last year. I PMed Theymos a few times about recovering my account, including loads of evidence that I actually owned the account, but he never responded. Someone ended up getting scammed for 12 BTC by my hacked account :S
Couldn't you prove the ownership? Didn't you sign msg? 2FA is coming in new forum, it will give more security
. IMO, an approval mail should be sent to the corresponding email of the account if there is change in email address, gives better security, unless it changed by Theymos or Badbear(Mostly when recovering account)
Kindly,
MZ
