The the symbolism comms system if you weren't aware (and the bad guys have done a great job of misleading people on the simplicity of it). - Is just using anything that's not direct speech to say without saying. Like using a pose, a hairstyle, a colour, a code word, a pattern of letters or sequence - anything that says without accruing evidence
e.g. in this article https://www.dailymail.co.uk/news/article-6947099/Melania-rebrands-Easter-putting-Best-slogan-eggs-White-House-Easter-egg-roll.html
there are a number of symbolism codes here. I typed out a long explanation of them but then deleted it… basically about whisteblowing against child rapists (sedated children) - and the gold we stole from the cult and media operatives we have waiting to be activated. - I'm still trying to figure out how to explain the symbolism comms in common usage each time because starting from the beginning of it requires a lot of time on how to read a sequence of pictures (or video timecoding) - knowing each colour in particular. - https://twitter.com/CodesUcq - check my pinned for some common ones (including how to read these ones)
