only real way to prevent scamming and such is if multiple entities contribute.
only thing I can think of is each guild have a go fund me page and the guild members can just donate towards 1 goal of 1 month worth of payment.
and that guild would submit it. if 1 person out of 10,000+ people holds on to the donations, we may have a second iteration of what happened to "the rebirth" private server where the dude took the money and ran. (over $15,000 worth)
40+ guilds on the server paying 1 months worth is well over a year's worth of playtime.
not sure how everyone feels about it but it sounds the most logical. plus it gives more leeway for people to donate 5$ or maybe 10$ instead of 25$ or more.
