I have recently received (and executed) a ban request. However, the ban request was supposed to send me attached a logfile of the recent chat. This did not work properly so now I simply take the logfile and scan every line for the mention of the username and attach those. The requesting user gets a report of the lines being scanned and how many have been sent to me, so if there are zero lines, something went wrong and the requestor can submit a trouble ticket.
