Is there any possible way to un-ban a profile?

What is considered referral code spam? One of those full on advertising posts with referral codes all over it like were posted when tradehill opened? What if it's a little more subtle? What about low content posts with the code in the signature?

I guess what I'm trying to ask is, is there any reason to not just fully ban referral codes? They're mostly just spam and don't really benefit the forum any. And then it'd be a clear enforceable line.

Just a thought.

The policy to not remove anything worked when the forum was small. Now that we have thousands of posts a day, we can't afford 50% of them being junk. The moderators are now instructed to be less tolerant of low-value posts.

Some guidelines:

1. Free speech - you can say anything as long as it is relevant and presented in a calm and polite manner. Swearing, SHOUTING etc. make your post more likely to be removed.
2. No zero value posts or threads, like "SELL SELL SELL"
3. No pointless or uninteresting threads.
4. No referral code spam
5. No NSFW content

First point is actually correct. I have seen my friends accounts  getting banned for posting irrelevant posts and over postings. For a newbie, there should be only 1 post a day. and the content should include from 50-100 words. Otherwise, there's a possibility of your account getting banned from signature campaign and from bitcointalk as well.

1. No zero or low value, pointless or uninteresting posts or threads.
