The idea for clubs are for members to kinda build their own audience and discuss what they want with the people that also like that specific topic. So, here are some more 'relaxed' rules for you all: (note, these rules are only for clubs)
Porn/Nudes/Shock Images - common sense. If you're mom didn't want you looking at it as a kid, it shouldn't be here.
If you support terrorists of any type, from any year/time, you're going to have a bad time. Don't do it.
Groups that represent nazis and support nazis will not be allowed. Feel free to talk about them in discussion, but we aren't about to make a new reich here on the PW forums.
There is a think line here, most opinions today are considered 'hate speech' - discussion is a discussion, but blatantly hating on a person or a group is gonna be against the rules. Best thing to do, make a closed club and select your audience.
If you're creating a club, you are auto-agreeing to the common sense rule. Keep it chill, don't do anything that would normally be considered wrong in the public or in front of jesus/santa/or whatever you consider to be held to high standards.
Have Fun With it
This is a new thing for the community, have fun and make it creative.
