The worst part is Markus stores his passwords in plaintext, or slightly better reversible encryption.
POF will mail a person their password. This is a security nightmare because basic precautions were not taken.
I just checked and POF is still able to reproduce and email me my password. I also checked the email I use for POF and there is no mention of this in any of their emails. If markus took this seriously at all he'd be resetting everyones password and have instructions to reset their email password.
"We have reset all users passwords and closed the security hole that allowed them to enter." This is a lie, I just logged in with my username and password. I wasn't even asked on login to change it.
