Joshua, I agree with your point, and also noticed that some of the responses seemed to be missing the circumstances of this request. It's not simply a matter of vetting your players because no matter how much vetting, whether it's strangers or your best friend, people can later get into disagreements over games & the game owner (GM) needs to be able to control who can stay. That said. Let me answer with practical advice on the matter. Don't jump to "copy/extend". First move the Players ribbon to a BLANK MAP PAGE and don't bother moving any tokens to the page, so there's not much they can do except drawings & typing in chat. Next say it out loud & write it in the chat room: "Joe, I'm going to have to ask you to leave. Please quit out of the game. This is disruptive." Whatever you need to say, just ask the person to leave -- ask them nicely, ask them firmly. They still refuse? Second step, inform the other Players in the game, "Due to a disruption, we need to take a short break in the game. Everyone please leave the game, don't feed the troll, and I will contact you on Roll20 Messages shortly when it is time for eligible participants to rejoin." Now you can quit the game and wait 5 minutes, check if the person is gone. If they are alone in the game room, with no reactions, and just a blank page to draw on, they will get bored and their trolling will have no effect. They will leave after a period of boredom. Once they are gone, Kick them on the campaign page and they won't be able to come back. Your campaign will have a new Launch / Join link, which your Players who are still in the campaign will be able to access in the usual way of clicking Join. If the offender is still not gone, wait 10 minutes and check again. You've wasted maybe 15 minutes, but this may be faster than doing "copy/extend" and jumping through hoops of resetting your macros, API, and so on. In most situations --- as a practical matter, realistically speaking -- you probably would not need to go to the extreme measure of "copy/extend" porting the campaign to a new campaign. It was an accurate recommendation based on, that is what you would technically need to do if you absolutely need to immediately and permanently cleanse the offender out of your campaign, and you can't stand telling the person to leave & you can't stand waiting the person out until they leave from boredom. It's rarely necessary though. In conclusion, Just because you need to Kick someone out, and that person is persistently in your game room on that day, still does not necessarily require you to "copy/extend" to make them leave, because there are other, easier, more practical ways to encourage them to leave. I hope this perspective helps you to find a different way to overcome this kind of bump in the road for a GM.
