What are some ridiculous rules you've come across on sites?

I've seen "don't be a homo even if you are one" on one site's rules list...like wth O-o

Also, on another site, you're not allowed to post in a topic if it's been inactive for 3 months+ even if it's high up on the main page of the particular board it's in...how do people expect activity if they don't let you post in topics that are already there?
