Bad idea of the day: an instance where all toots are encoded with a vignere cypher, with the key chosen at random from a dictionary every 3 hours. The key is kept secret from the users. If a user determines the key & types it, s/he is put in a "hall of fame" list & the key is reset.

@enkiv2 But…Vigenere is pretty easy to break under chosen-plaintext (which you get by being able to post at will), isn't it? And with a dictionary as basis for keys, it becomes even easier.
But it would be a fun exercise to build some tools using the API, so if someone builds it, I'd use it just for that purpose.

@redacted
I'm thinking maybe only other people's toots will be shown in cyphertext -- i.e., collaboration and/or statistical analysis is necessary.

Also means users can screw with each other by posting stuff in rot-13 or encoded with other substitution cyphers.

@enkiv2 True, and it might be good if you had to post proof of your own implementation alongside the key (e.g. a Github link or short description).
