There are three steps in the Unresponsive Profile Manager process, aren't there? Leave a message on the person's profile, send a Trusted List request, and send a personal message. So if the case you asked about is this type of thing, you should have a record of your TL request, and your comment should be on the person's profile. I haven't been through the process, but my guess is that the Mentor (or whoever intervenes) will, as the Honor Code requires, assume you are honest. But if you have records of the other two steps, just to be safe you could send one more PM and this time keep a record.
