Why am I not allowed to post in the other forums?

I have just come back to this account and the forums after a break and I make a post and a reply or two and I’m suddenly not allowed to post on anything but the technical support. It won’t tell me why, just that I’m not allowed. I have had no notification or email to say wether I’ve been muted for some reason. Can someone please tell me what going on as I’m incredibly confused. I had a VPN that I turned off to see if that was the issue but I don’t think it is it didn’t work with or without. And yes, I have read all the support pages and put in a blizzard support ticket that never came back to me. I can’t find help from a real person unless it’s on these forums. So please can someone tell me why I can’t post?

Edit: spelling

Says you have 3 posts. So I guess either, you’ve accidentally changed forums to here where you don’t post. Or logged into the wrong account.
