yeah this seems like a cat-and-mouse game, especially if there’s sufficient incentive/money

Weird ones like the ones about the letter wars, eg r/theLetterH

And generally communities about movies and tv shows, eg dedicated series subreddits

I think it’s the length of the password that affects log-in from mlem. I changed my original password to a shorter one and I can now log in. I also did a couple rounds of changing password (1 more long and 1 more short; both only have -, numbers and letters), and I was only able to log in with the short one. I didn’t experiment on how long the passwords can be for mlem to be able to take.
