The Mudcat Pre-Paid Absolution Card would have to include some Mudcat specific sins:
Not searching the DB before requesting lyrics.
Telling a particularly stinko pun.
Getting sucked in by insults from gothic architectural features.
Winding up Catspaw (this usually is done by submitting a message).
Sending embarrassing photos to people who will inevitably tell the whole world, and e-mail it to half of them.
Got any more?
