And yes, I know people will say block keywords and communities, but people don't understand some communities have rules and people must follow them.
The “rules” should be more like guidelines to suggest to posters what type of content the intent of the community is, not what type of content is permissible.
I totally agree. Rules number 1, 4, and 5 are the most important, in my opinion. I'm not saying that there shouldn't be rules in the communities; there definitely should be rules. Guidelines for what to post instead of what not to post will probably be more beneficial.
