This one is new for me:
Your IP address has been blocked for an hour. Sorry for the inconvenience.
What for is it blocked? I refreshed the page and this message showed up, my UID is: 1035511
The first time I've seen it. I'm not using vpn or anything and haven't been in chat since 8 hours or so.
IP addresses are only blocked if they are hitting the site much too often. It's a primitive DOS protection.
In your case it looks like user 91380 (Seuntjie) is logging in over and over from your IP address. Are you using his bot perhaps? If so I think it's the bot that is getting your IP address banned.
Edit: specifically, your IP address tried logging in 25 times in a single minute, at these timestamps (UTC):

Some seconds there you were doing 5 logins per second. That's what got your IP address banned...
