I don't think these have been posted. If they have, apologies for the dupes.
These are on Reddit /greatawakening/. I've read there are "helper Anons" who help steer Anons in the right direction on Q drops. It's speculated these posts might be from a "helper Anon". I don't do 8ch and haven't seen the original posts. Perhaps if some Qsters here visit 8ch, they might have more insight to the posts.
I found them interesting. There might be nothing to them, just someone pretending to have inside knowledge.
One thing to note: in the posts at the second link (Part 2), there is a line that ends "...it sounds like MOABs are coming left, right and centre." The spelling of "centre" is British. That puts more doubt that these are genuinely from anyone "in the know"--IMO.
