1. The sub is not allowed to use any proper nouns in chat (easy enough to check)
2. The sub will not be allowed to use a question mark when asking something, but must still be grammatically correct.
3. In each message to his/her Dom/me, the sub must list one erotic body part (cunt, tits, cock) in another language not spoken by him/her.
4. The sub must catalogue each time they touch their genitals, no matter if it's to use the restroom, or if it's to scratch and/or itch, or even if they brushed it by accident.
5. The sub will not use the word 'no' whether as an answer, or even hidden in another word.
6. The sub must answer to all posts by their Dom/me within x seconds.
7. The sub must use x amount of words per post. No more, no less.
8. The sub must send his/her Dom/me a poem every day, written by them, of a predetermined length, using only words used in the last chat.
9. The sub, regardless of gender must paint their toenails a new colour every week and send a picture to their Dom/me.
10. Every month, the sub must choose someone on this site to seduce and send a screenshot of their chats to their Dom/me.
