Q is an anonymous source, posting initially on 4Chan, then 8Chan, and now 8Kun messaging boards, since Oct 2017. QAnon claims to have highest level intel clearances, and that the information dropped is part of a military operation to undermine those that have co-ordinated to retain power and control over government, media, entertainment, internet, etc.
Q drops are often coded, 'breadcrumbs' which other 'Anons' on the messaging boards dig into, research further, assembling into expanded threads of information. The information assembled by the group, could be considered the largest intelligence drop in history (assuming Q is genuine). Most of it is open source... although there are a number of original photos which appear to be taken by someone close to the President.
There are a number of "Q Proofs", such as 'zero delta' posts - posts at identical time to Trump's Twitter posts.
Many here and elsewhere think it's a big scam... that may be the case, but if you have the time, there is some incredibly interesting information contained in the posts.
LARP, Psyop, whatever... would the outcome be any different if it really was a military intel operation?
If it's some LARP posting from his parent's basement, it's the most sophisticated LARP in internet history. Hats off to whoever has managed to keep it going since 2017.
Not that he was likely to reproduce anyway (soyboy) but we should acknowledge that deserved a Darwin Award.
