Would you actually be able to do it full time? Sounds like an easy way to burnout after several days at most, and it would only be a matter of time before you would get banned. Your posts in that experiment aren't that bad actually (compared to an average stake.com/yobit sig-spam shitposter), but I bet your post quality would start suffering soon, to the point of getting eventually banned.
I would probably be able to do it full-time. Lowering the speed, you can start to get into the mind-numbing state of ennui and start pumping out the posts with automation. Considering most of the shitposts are just vague, generalized bullshit that are either one-liners or just jam-packed with false rhetoric and repetitious nonsense, it isn't that difficult to just repeat essentially the same things about "the bitcoin" over and over again.
