You don’t need a monthly subscription to provide money for ONE person to spend some time every couple days to go through the exploits that are reported on servers and deal with them. If any player can log into single player and teleport to and area to test something in a few minutes, an admin could surely do the same thing.
People aren’t asking for admins 24/7. They want someone to actually ACT on these exploiters and cheaters when there are reports on them.
