Some people seem to think that my whole isp is banned? I dont know what any of this means.

ISP = The company that you pay to let you connect to the Internet. Sometimes when some people are really bad on IRC it makes the people in charge of a network ban the whole ISP, so all users of that ISP cannot connect. It doesn't mean that you have done something wrong. It just means that someone using the same ISP that you do may have done something wrong and then decided to avoid the bans placed on him. This usually results in the bans being issued again or a stronger ban placed on, and usually for a longer time too. Somewhere along the lines innocent people will get affected by it.
