Sorry, no - not at this time. For all we know, you're not in an internet café at all, and you have multiple Battleye GUIDs at your disposal. I'm not saying you *have*, but it is possible. Hence the IP ban is a 'belt-and-braces' approach that safeguards the server a little more than would be the case without it.
When/if abedbawsxx files an unban request and explains/apologies/demonstrates awareness of the rules, we'll talk again. But in the meantime, sorry, the IP-ban stays.
Please don't be angry at us. Be angry at your friend, if he has spoiled your fun by his thoughtless actions.
