According to IRCHighWay's Acceptable Use Policy, channels founders are to do as they please. Generaly speaking, it means that the Network Staff does not and can not interfere with channels matters.
But what can you do then? The best way to get a channel ban removed is to contact the channel operator that banned you in the first place. You can do this by the mean of a private message or a memo (please read /memoserv help for more information).
If you have no idea who banned you, there is only one way to go: you have to contact the channel founder for assistance. Once again, this can be done by the mean of a private message or a memo.
Of course, you may not know who is the founder of a channel you are banned from, there is a command that you can issue in order to find out his or her nick:
/chanserv info <#channel>
This command, once issued, will give you some information about the specified channel, including the founder's nickname.
Keep in mind that the channel founder may not be around, patience is a virtue, and that he may or may not remove the ban that prohibits you from joining the channel. The founder is the law within a channel. There is no point discussing the decisions he or she makes. Basically, you could be banned from a channel just because the ops do not like you, that's perfectly legit and the Network Staff will not do anything.
However, there are a few exceptions to the channel founder and ops almighty will; as I said earlier in this article.
What are these exceptions?
If the decision of a channel founder, admin or op is against the network's Acceptable Use Policy, the Network Staff is allowed to interefere and can therefore take action if they feel fit; upon the results of their investigation. It is only in such situations that you should go to the #abuse channel and submit a request for assistance.
I think you should now be able to answer properly if you ever get banned from a channel on IRCHighWay. I wish you good luck and although you are now prepared, I hope you will never find yourself in such a situation ;)
Have a nice week,
If you are banned from a channel where you are an op, depending on the channel's settings, you may or may not be able to overwrite the ban or to invite yourself.
Assuming that your access level is high enough:
To unban yourself: /chanserv unban <#channel>
To invite yourself: /chanserv invite <#channel>
