The Hot Servers list is automatically generated so I'm not sure if they can do that. But, I do think the Hot Servers list should be updated so that servers that aren't even online are excluded from the list.
If i were you, i would advertise your LEET server in any place possible. Recommendation: Advertise your server info, and what it has to offer onto #community servers on the official LEEt discord server.
I find constant voting (and i mean CONSTANT voting) can help. Get yourself on every server list, and vote every day. Cant post links here, but theres 2 major ones that if you vote everyday, you have a decent chance of getting people.
