helpers are almost constantly being PMed from players with haxusations, tattle-telling, requests, and trying to earn brownie points, lol. You should have seen how many PM's I got when I got inf money. Every day it was 10+ people messaging me. I couldn't answer every single one. But I saw most of them and responded to the ones that were most significant. Just because you aren't responded too, doesn't mean you go unheard. Trust me on this.
I would also like to add that when I've been on, they usually stagger themselves on the servers. Meaning One mod or helper is on tmd-1, one is on tmd-2, and so on. Sometimes they do get together to take a break and have some fun. They deserve it. They work very hard, and that is something people need to really realize.
