Going through Abu Jafar post history, I am 90% sure it is a machine learning Bot working with a reinforcement learning algorithm.
It has a 3 step process which is repeated.
1 - Start a new thread (with an old idea as a topic)
2 - Single sentence outlining the new theory
3 - up to maybe 3 posts to keep the thread moving
repeat
Very low effort for a person.
The level of reaction from other people is probably the reward which it tries to maximize.
Notice how bad its ability to actually engage in discussions are, it has a very bad concept of context, which is very common to most chat bot logarithms even now.
But you guys are helping it learn very well, soon the whole Flat Earth Society will be automated.
