The fun part is even if all social media platforms know your 'code words', they'll have to ban ALL posts from EVERYONE that use the words 'Biden' and 'science'. They won't know which are real sentences or coded sentences. They're entire censoring system will fall apart. eg: "Trump proves Biden science" "Biden Science 2020" "Biden will have to leave presidency because of Biden science" "New evidence pouring in on Biden science"
PRO TIP - To not get banned on social media, exchange words like 'Biden' for 'election' and 'science' for 'fraud' (and so on). The fact-checkers and censors won't know WTF you're talking about. eg: "In 2020, there was evidence of Biden science". (they'll have to ban THOSE words now too)
