Garry's Mod server ranking
Average players online over 7 days.
No ranked server here yet.
How does it work?
Each player can vote for a server every 3 hours. Votes from the server's team show but do not count, and the ranking restarts on the 1st of every month. Last month's top 10 keep their badge.
A clean ranking
VPN and proxy detection, per-connection limits, captcha, vote-spike monitoring and cancellation of fraudulent votes: buying or faking votes does not win a place.
