Passwords should be sent as hashes, compared with the hashes on the server (read: your plaintext password shouldn't exist on the server, & your plaintext password should never be transmitted)
Or at least transferred securely (https rather than http)
While I don't have proof of plaintext passwords being stored on the server, I assume so given their transmission
Edit to clarify: I mean passwords for elementsthegame, not the forum
Edit: proof: you can retrieve your password by logging in through kong, which means the server sends your plaintext password to you without receiving it. Which implies it gets it from a db
