I see sometimes that it seems to be that users on bitcointalk can guess pretty good which accounts were sold in an auction that ended. Simply because the forum shows them the accounts with changed passwords. So what i wonder if thats a feature that makes sense. Password changes does happen when the forum was hacked too and when someone is uncertain about if an account was hacked, he can ask for signing an address that was posted some time ago. It would be more important that "Edited" notes would be there, which i lately miss somehow. Might be only because of editing too fast though.
So what are your thoughts? Is it a good thing to show that the password was changed lately?
There should be some sort of logs such as last failure account login, so that moderators can easily know that how many times the hacker guessed and try with brute force passwords. And also regards to your question that, yes it is a good thing to show that the password was changed, at least the victim will com to know that his/her account has been hacked.
