I am not a regular poster on the gambling section, what if I start posting in the gambling section now? Will you consider this account to change hands in case I am forced to make a post on the gambling section due to the signature campaign?
Changing the password or posting on the gambling section doesn't prove the account changed hands. Need more solid evidence to tag the account.
Correct on all of that. Being in a campaign where you have to post in certain sections can definitely influence where you post--whether you like or know anything about those sections or not.
I have not looked into this situation in detail, but one thing I can say is that if there's a scenario like this where a member has woken up after a long time, joined a campaign and so forth, check the style of that member's posts. If there's a language switch or a shift from good English to typical bounty hunter English, that's a dead giveaway and I've seen it many times.
As far as Iranus is concerned, the evidence I've read so far does point to the account changing hands, but I'm not 100% convinced and thus am not going to tag him.
I am not a fan of digging accounts and I really do not encourage it too.
Then don't do it. But please don't discourage others from doing it. My own detective work in the past has turned up lots of sold/hacked accounts, and you've got to be aware that there's too much bullshit going on in the forum that if it weren't for those members delving into suspicious accounts, people would be getting away with everything under the sun.
