I doubt it. Looking at his post history and long inactivity, it seems just like another alt account awakened for the sole purpose of sponging a few dollars by promoting a scam casino and probably cheating in contests and promotions.
That is what I thought too, it was an alt-account trying to join a signature campaign knowingly to promote a scam website such as the 1xbit scammers.
He doesn't come and complain about the tag based on his post history but I don't know if he has sent you a PM or not to explain the problem. But now it looks like di is really making a big mistake for his account regardless if it is alt account or main account.
It seems that 2 DT tags are enough to identify him as one of the people promoting the scam site even if only one application post and one general post.
