Note - @Solosanz you Registered your account at 3th April 2020. Then you become inactive and wake up again in April 2022. Those are about two months ago from now. But in the meanwhile you have become a storehouse of knowledge. The matter is making us think a bit. Couldn't it be that this account is an alt of yours?
It seems the 2nd option which BitcoinGirl.Club mentioned is more appropriate for him, his writing style and knowledge about the forum is referred that he is a very old member.
But without any proof, we can't claim it, and having an alt account is not prohibited though.
Whether he is the alt of someone or not, is it ok for DT1 to add someone on their trust list if he burst some scam!!
If a newbie came and burst some scam frequently then does it mean he is safe to do business/trade?
