Calling the UC Davis police, while a good way to vent, will have no effect. Nothing that has been discussed in this thread suggests that any criminal enterprise happened through any agency of UC Davis. None of the strikingly competent investigators who have done their homework on this issue have said anything about using school computers, school facilities, or any other element of the school in this effort. The UCD police will ask if the crime happened on campus, or involved campus related computers, and then tell you to call your local police. They might write upis a ticket if he parks illegally on campus, but they sure won't give a damn about your missing mooncoins or anything else that they can't wrap a nightstick around.
One of the IRC IP addresses resolved to an on campus location. Plus, most universities are interested if their students are committing federal crimes since it would result in egg on their face if they gave a degree to a felon. Both the FBI or the USPIS can investigate wire fraud, so a polite note to either of them would also be productive. Filing a local police report would be useful for documenting evidence for a civil claim.
@ElectricMonk: the original sentence (a very meandering one in your defense) was:
If his claims to be college student (although one who spent too much time star gazing and not enough learning to craft a coherent sentence) didn't bear out, I would expect his IP to resolve to Lagos or Moscowboiled down it yields
If his claims to be college student didn't bear out, I would expect his IP to resolve to Lagos or MoscowHe was trying to say that upisdown resembles the classic Nigerian or Russian scammer archetype. When he says "I would expect", it means that if he had to guess (without foreknowledge of the where the IP address resolves to) he would guess Nigeria or Russia.
