You're pretty good at finding these guys. TBH I don't spend a whole lot of time wading through Gambling section megathreads, but these types of posts should still be deleted as they are meaningless blather that contributes nothing.
I don't spend much time on this either.
I only get sensitive and check when the structure of the post seems strange to me (of course, there have been many times when my intuition has been wrong).
I ran several of his other posts through detectors. They come back as Fake in Sapling but Human (or mostly human) in the other detectors.
I have to say about this user and his posts that I also encountered cases of combining human and AI when reviewing, and some posts were even recognized as suspicious by two recognizers, but I avoid declaring that post until it is recognized by all three very reliable tools (almost in my opinion) or more.
