Here is the 8ch.net thread link:

Do you think Q is coming back?

The story is allegedly that only the first few days of Q posts at the end of October were from the "genuine" Q (whatever that means) and that subsequent Q posts were by others, perhaps two or more low level staffers who were not supposed to have access to the information being posted. Allegedly said staffers have since been fired. It is also unclear whether the "MegaAnon" who posted assertions about this was the "real" MegaAnon (once again, whatever that means).

Furthermore, the current MegaAnon apparently did not say that the material posted by the recent Q was false or misleading, just that it was not posted by the original Q, a possible implication being that too many "beans" were spilled, i.e. too much was revealed too soon about what is going on, to the possible detriment of the operation, so that further communications of the Q type may have been suspended. Oddly though, or perhaps not so oddly, I find that today's tweets by POTUS have a certain Q-like sound to them. Curiouser and curiouser.

Example POTUS tweet:

So now that Matt Lauer is gone when will the Fake News practitioners at NBC be terminating the contract of Phil Griffin? And will they terminate low ratings Joe Scarborough based on the “unsolved mystery” that took place in Florida years ago? Investigate!
