You will find any forum that can ban is logging IP's. It is not distributed to any outside source. IP's are not traced and will not be traced. There are maybe 3 forums out there that do not log IP's but the majority do. If you are concerned get an IP changer.
The plus to this is the server is located in Holland not stateside or in Canada where that may be an issue. IP can only be traced back to the internet provider. That is all.
