I love the idea, but doesn't seem convenient. Do you use Discord or plan on creating a R* crew?
I do this on one of the Discord servers i'm part of; sometimes (rarely) someone will post that they are being griefed, so I will join them, can be pretty fun, especially if you don't join their posse, as for reasons you stated. The last two times I've asked for help, nobody came to my rescue ... and I lost all my pelts, haha, it happens; why a lvl 120 goes out of his way to attack lvl 29 me trying to hunt a cougar in the forest, idk.
