Those rules were written for one of Shaggy's other sites. He copied/pasted them here (yeah, sorry Shaggy. I dobbed you in
)
The "gay" rule was added because a lot of immature children there were using it as an insult aimed at each other and because I (it was me who wrote those rules) hate that word used to mean "stupid" or "idiot" and decided to make it forbidden on that forum. I recently rewrote the rules on that other forum and have softened the "gay" rule to only being forbidden when the word is used in an insulting manner.
I honestly don't know what Shaggy thinks of it and if he would punish someone for using it here to describe a thing or situation (using it to describe a person would be flaming).
