Greetings from Nigeria, his idea isn't really appropriate and I agree with your statement about him creating a testing platform to test his AI comment activities.

AI shouldn't be used to replace human beings, when AI came into existence not long ago, I had a feeling that the disadvantage might be more than the advantage because these days human beings are lazy, machines and robots are in companies doing alot of work human beings are supposed to do and now AI came into existence to make things more worst.

The idea of xpilar making AI comments to boost the engagement rate of this platform isn't a positive one at all, AI is now getting rampard, I agree with steemcurator01 who said that the AI posts should be set 100% to null if xpilar intentions isn't to generate profit.
