Suggestions are always welcome why would we ban you for that?
From what I can see you are asking for:
1) A spam thread or section where people post random stuff.
a. We have had this in the past and it took away from the forum way too much. People went into that area and never went anywhere else, the board’s activity died in the other areas and frankly those other areas we want active, much more then a spam section. AO is mainly for intelligent discussions, while we want cut loose and fun it isn’t necessarily a spam section that will bring it. We would love to consider an alternative to this and maybe other members can weigh in on a good way to do it. I will suggest that the clans are allowed to do these kinds of things in their respective areas so maybe consider joining one of them? That way you can cut loose and have fun with your peers without issue of breaking the rules.
2) You want a blog section!
a. We have that!!!! In your profile you have the ability to write blog entries and have people leave comments for them. Due to drama and other junk the main boards just aren’t the place for it but we understand the need and want so that is why you can do so in your profile! Let me know if you need help in setting that up
