Ok so I got proxy banned and served my time but even when spam cop says I've been de-listed, it still doesn't let me on the server. does it have anything to do with the server updating?
there is no "proxy ban" that requires you to "serve time." the proxy-check system is not there to punish, it's just a precaution.
if you're listed on spam cop, you will not be allowed on opticraft until you're off the list.

i don't have the ability to look into your problem more; you could be on a different proxy list now. optical will have to check into it.
