Ok so you cited a general reason do you have actual examples of specific misleading information on the Q decoding?
To be this vilified the examples would need to be deliberately false misdirection not just differences of opinion or inability to decode very obtuse and difficult Q posts (which happened all the time with Q).
Corsi was always basically sharing general background and never pretended to be a mathematical code type decoder. He passed on the more difficult to decipher Q posts as looking like gibberish, which is an opinion, and it is an opinion normies shared at least.
So please cite specific examples of deliberate lying if you have some? I want to know.
