You are free to agree or disagree with any rule, but you are required to abide by them in order to be a member here. While I wouldn't necessarily say that TBT is marketed to kids, it is meant to be suitable for a diverse range of people, including kids. That is why we have many rules in place with the purpose of ensuring that TBT has a "family friendly" environment. This includes sexual material, obscene content, and profanity. Besides, these rules are not solely in place because of younger members. We have a standard that every post should meet in order to keep our discussions somewhat professional, which is also the reason for our post quality rule. For example, I may not be a kid, but I still don't want to see pornography, inappropriate discussions, spam, or f-bombs in every other post. There are many other online communities that have no filters on posted content, but that is not the type of forum I'd like TBT to be.
