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.
There are so many sleeper accounts out there that are used sparingly by the puppeteers in the hope they will not be picked up as farming accounts but eventually most of them lower their guard or let greed get the better of them and then they get tagged. That is what happened in the case above.

Until recently, perhaps he had not realized what consequences he had received on his account.
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.
