Custom is running this server, but none of it is his - it's all Skeletal's, but Skeletal can not run it as his internet is horrendous.
I'm not saying Custom is a good host either, though. I have to agree that he is inattentive and doesn't actually care.
This server is not for people who actually want to play.
If you want to complain to someone, complain to Skeletal, because it is his server with Custom as the host.
