I looked at the post gap several months ago but had discovered aTriz was able to sign a message from a prior address after being questioned. Even though I do realize private keys can certainly be sold (and possibly stolen), this is pretty much the standard way to confirm the account is under control of the original owner.
However, as I re-think this, the signed message was not dated and should not have been accepted as proof.. for all I know it could have been an old copy/paste signed message that the original owner
could have sent to someone in 2013/14. The 2013/14 version was pretty active in trading, and a signed message like this could have easily been requested back then and may not have had a date.
I may be overthinking this, but to be safe,
aTriz, will you please sign another message from the address below,
with today's date.
Your funny. You might have noticed, I changed password before I start managing Campaigns and that was for my own safety.

Also, I'd like to point out this post, which was deleted at some point
after 2016 (maybe whenever the new owner took over?):
https://web.archive.org/web/20160412055259/https://bitcointalk.org/index.php?action=profile;u=135920;sa=showPosts;start=520About half way down the archived posts, you will see the
old aTriz make a post in a Crypsty thread, signing it as "- Adam"
In 2017, after this aTriz account was resurrected, an apparent dox happened on
current aTriz which apparently claimed his name was Ke* Ma*. (I'm omitting since this is technically not "Investigations" but those who understand will know what name I am talking about).
Another threat of this same dox happened with alia due to, according to aTriz, a paypal-to-btc transaction he did with alia (naiveness??) which he could never prove with a transaction and this is what apparently exposed his personal information (Ke* Ma*) to alia.
I'm starting to think the account actually did change hands.

Even if it did, what's the difference? The new aTriz would be the one who built up the reputation, and account sales were less frowned upon back then?
