People could also agree on a language to use in Reddit that uses a ticker to get through the approval system (e.g. AAPL) but then in the content of the message, indicate the ticker actually being discussed by look at the first letter of each of the first few words of the post.

For example

Subject: AAPL is awesome

Message: Generalizing My Equations in a very interesting way ...

When the mods catch on this and write bots to deal with it, we invent a new language. It's faster to invent codes than for mods to write bots so they can never keep up.

My favorite example of filter evasion in recent memory is "$SEARS" being used for "Roblox".

To your point, a "secret language" is only useful if it can evade detection and remain in use.

The former is difficult because moderators spend an inordinate amount of time perusing the subreddit.

The latter requires a sufficiently large "speaker base" in order for messages not to go unnoticed, discouraging speakers. This can be solved by making the "secret language" more accessible (that is, more obvious to new "speakers", but also mods) or by sharing the keys to the language through other channels (which, to some extent, defeats the point of using the subreddit).

What tends to happen more often is users using emojis to bypass filters. E.g. CC $eye_emoji V to represent CCIV, or the SOS emoji to represent SOS. Another strategy is obfuscating the message with interspersed noise, E.g. "A-,-A---P,,,L".

Generally speaking, these have the same pitfalls as mentioned above and are caught quickly.

You’d need some other channel to communicate with the tribe to exchange the new ciphers, by which time you might as well just use that other channel instead of reddit.
