But I do see Sixteens point. This feature can be taken away later on, but as of right now, our previous community group had 20,000+ Members, and our current on only has 7,300+ and it's been at the 7,000 mark for almost a month and a half now.
Players are already required to join the group and favorite the server. If we make it so they have to favourite/VIP for them to be able to get rid of it, then it encourages them to stay in the server.
Do note:
Members who do get the favorite option are often regulars of our community daily. Those who are regulars have favorites. Those who are often not regulars, will only be there temporarily, so the jackpot feature is not something they should be bothered by, such as our regular members whom are on every day.
So limiting it to fav's/VIP members, is better off because those are the regulars of our server, and they would be the ones whom want to turn it off in the first place. Not regulars.
So that's why I see limiting it to our group members and favorites is a good idea.
