I've been banned from posting for the past two weeks because I posted a photo of a young guy (age as yet unknown) wearing an afro wig and sunglasses. The photo was in Sharphedin's "Afroman" thread.

Admin enforces at will. How you find out about the unwritten rules is by reading about them on the discussion boards or by breaking them as you apparently did. If the picture was of a minor, that is against the rules. TER is an adult sex board site and pictures and discussions of children are innapropriate.

Does TER give warnings? That is not my experience but I could be wrong.

Sharphedin posted photos of AA guys that I thought were unflattering, and I believe his intent would be regarded by many as being racist. I posted a photo of a 20 year old guy wearing an afro wig and sunglasses. An admin thought the guy was under 18, and so banned me. Sharphedin was not banned.

He's not really banned. He lost his posting priveledges for a week. Boohoo. Cry me a river. Did anybody miss him?
It takes a really serious offense for TER to actually ban someone.

BFD. Is that the end of thd world? Were you still able to read reviews? Isn't that what people pay for? Nobody pays to be able to post on the public forums.

If posting privileges aren't any big deal, then why are they only available to VIP members? Just about every forum I'm aware of is free. Here you have to pay to post.  

...Reviewers only and Providers only boards. Vip is required to see certain parts of the ladies profiles and to use the PM system but posting on the boards is absolutely free. Vip is required to use the search by reviewer function but posting on the boards cost nothing. I'm sure I'm leaving something out but I have no doubt that posting on any board excluding the RO and PO is a privilege afforded any non paying member of TER.

I'd rather have incorrect spelling on a few words than completely wrong words thrown in by the iphone. Have you not seen those "damn you autocorrect" bits all over the internet?

Of course there are other restrictions for joining those boards, but VIP membership is definitely not one of them.
As you mentioned, VIP is required to read juicy details and certain parts of the provider profiles, for access to certain search features, and for using PMs. The thing that you left out is use of an alias.

I wasn't thinking and completely by passed that once you have the required number of reviews (and TER deems you qualified) you can post on the RO board whether you are a VIP member or not. Same for the ladies. I'll blame it on a senior moment. That's my story and I'm sticking to it.

...but I don't need a machine telling me what I meant to say.
