The solution to that is to use memes and bad grammar. I am not kidding. Keep your messages really brief and have a community of people that talk in a very similar fashion to one-another.
I think reading TheShadowBrokers posts[0] is really interesting. Because they use really bad english. But it's consistent within one piece of text, but not always over multiple texts.
The only reason i can imagine they're writig this way is to foil stylometry.
I think is how the birth of leetspeak came about, no? And why still a lot of "read me" files for pirated software use poor grammar.
Another option is to use translation services, en->fr->ja->de->en. Reread message -- does it say what you mean? If yes, go for it! If not, modify as needed.
