Why does it say I am banned?

I've just posted an introduction and the little image next to my name says I'm a banned member and I don't understand why?

Hi, sorry about that I don't know why it's coming up with the banned sign, I must have put the link in the wrong section. I'll find out why it's doing that and then I'll sort it out

I think I've sorted it now, I'd put the sign for Banned members in the New Members section by accident. Sorry about this

Ok, thank you
