I am logged into the site which is clearly seen with my nic and profile...when I go to ANTY room it changes me to GUEST and then I cannot enter any room...I have never been banned, do nothing to be banned, and not been a frequent daily user but do monthly for past 5-7 years...I definitely have no reason to be banned, or a guest....using chrome , with no problems at this site except for entering any room...when I try any room in small print it says something about I'm either banned or not logged in, which makes no sense, since I am Logged in and I have NOT been banned NOR should be for any reason..
I run into this issue now and then as well, but have been successful by logging in through the backdoor at chat.buzzen.com. Hope that helps!
