People are experiencing protocol errors. The fix is to /register to change the way you login. Everyone joins as a guest player until they /login. Do this today please:
1) Login to the server the normal way (fighting protocol errors and server keys)
2) type "/register password password"
Instead of typing the word password, type what u want it to be. Passwords cannot contain spaces, must 4-8 characters, but can be anything you want.
----
Play in offline mode. If after joining the server you are not playing under your normal username and belt color, type "/login username password". The username is your username. The password is the pass you used to /register with.
