I kind of doubt that there are going to be enough reports against a so called "early puller" to get them sent to jail. Sure there will be a few butthurt people who may report someone they felt pulled early, but I doubt the number of reports against the individual will warrant going to "jail". Also, if the right click report is supposed to pretty much be targeted at eliminating RMT, it will be pretty obvious who is RMT and who isn't considering RMT have the keyboard smash names and the rest of us have names that actually look like names.
I don't see the right click report function being reconsidered and taken away due to people reporting early pullers. Honestly, I don't think an early puller will have enough right click reports against them to warrant them being sent to jail in the first place.
Edit: To add to this, I feel that everyone should be patient and wait for as many people as possible to arrive to kill a Hunt. They only spawn ever so often and, to me, it's just the courteous thing to do. Thankfully, I'm on a server with very courteous players (and plenty of available housing *hint hint* *wink wink*). It's pretty obvious when is the right time to pull and when it's a bit too early. If the hunt has been relayed you will of course see people asking for invites in /shout. When the number of shouts for invites becomes few and far between it's a good time to /shout a pull time and have that be 2-4 minutes from the current time to allow stragglers to arrive, or simply /shout "Anyone otw?" ....... If no response, then pulling is completely acceptable.
Honestly we're all adults here. It's pretty obvious if you're pulling a hunt mark while people are still asking for invites, which is a good indication that you're probably pulling too soon. Obviously, everyone will play how they want and that's also acceptable. So, to finish this up, if you're on a server where early pulling occurs frequently, I'm sorry you have to deal with that. There's plenty of room on Mateus and we would love to have more courteous players on our server!
