Please realize that we cant tell you exactly why you have been banned, or for how long. Only the network admins involved can help you with that, so we suggest going to the website of that network. All we can do is guess and possibly make suggestions to help you stop doing whatever it is they dont like. In some cases a user may not be the one specifically at fault, but is caught in a ban caused by others with a close ip.
LiQuiD9, i noticed that it says "no ident response" "flood clones" so the problem could be that there are a lot of flood clones and they insist on being able to get an ident repsonse from everyone/everyone on certain op ranges to stop the annoyance. Try this thread
sasori, without even knowing the exact msg you are getting, or even on what network, we can only suggest going to the website of the network involved to look for info
