This basically sums it up.

Killing others repeatedly(especially friends of yours) is an offense, and when you say "mini-riot" it sounds like you went about it in a very quick way. Does that somehow not constitute an advantage? I'm sorry that in the end you were the one punished(in should've been all or none... But maybe you got more kills than them, labeling you are the booster and them as the boostee) but overall you did boost and that is the punishment for it.

Don't blame it on the staff team. They made the decision to reset you, and now that's how it will end. Writing another ticket to them, assuming you've written one already, will not help your situation. This would've happened regardless of what staff were online, it isn't like you need some friend in staff to help you out, because while they can attempt to ignore it the others will not.

This should really be a lesson for everyone... Be smart about how you PK. I've had opportunities where I could've killed a farmer 20~ times in a row if I wanted to, but I didn't because of the possibility of being misunderstood. You should be cautious, because ultimately things can be misinterpreted. Graal is innocent until proven guilty, you should leave no doubts as to where you are. It's very safe to say you crossed into the danger zone, and that's what happens.

Pretty sure you also get an autoreport after an amount of Pking the same person over and over again without killing any other.

Well, ye' learned something. Pking your own friends 200-300 times can count as boosting. Even if you were simply sparring/pking for fun out in the open, it can be unfair to the rest of the pk community, for reasons you should know by now after having read all the feedback.

You want the staff to better-review your situation, but staff don't do that and never will, especially for an offense such as boosting. I'm pretty sure you were aware of boosting, and I believe you should have been more aware of what you were doing pking your friends 200-300 times.

Two friends along with the occasional people that run through can count as boosting, because you had a lot of kills with a small group of people altogether. Two people had been worth 200-300 of your kills, surely that seems a little wrong.

There's nothing anyone can do. Just start over and have fun. Try new things, don't let your now-nonexistent stats hold you back.

This is the problem, I did not even get 2 warnings, and the first was just not helpful as a warning when you get some minutes later a Bann. I'm not so stupid, and keep going, even though a warning has come, so please..

From what I know boosting is an instant stat reset and ban as soon as someones available.
Could have just been a new gp that didn't know how to handle the situation yet and then received guidance on what to do from a superior which would explain the sudden ban afterwards

Nobody still can not explain why my spar score was also reset

Not sure if this has already been mentioned yet but, u had 162k kills yet didn't know boosting was illegal?

Cause you are not giving us the full story, one of many reasons why (and I have told you several times now) we do not discuss bans/in-game conflict on the forums.

Looks like you already got your answer and nothing you say on here will change that.
