IP Ban
From Pool's Closed Wiki
An IP Ban is when a Moderator of Habbo Hotel bans your IP Address. IP means Internet Protocol.
How to get Unbanned:
IP Bans are very hard to get rid of, but it is always possible. One option is to change your IP Address. This might be able to be done manually, depending on your computer & your ISP, Internet Service Provider, but you might have to contact your ISP to request it to be changed. There are also some tools that can change your IP Address. You'll have to find those tools for now.
Another thing you need to know is that a IP Ban is different than a Shockwave Ban. Re-installing your Shockwave program will not fix a IP Ban, but you should always see if you have a Shockwave Ban before trying to change your IP Address.
