source cant put a “fake” redirect up. it can be set up if you join a full server you get a popup message saying this server is full, try our GG server or w/e you want it to say. It does not automaticaly push the client into a server they dont wont to join. It also does not show a near full server on like d2, and pushes them to like 8ppl on cbbl like 1.6 does 
but i will say they work hella great. The redirects that i’m running will show me the player name which got redirected, and i can watch in hlsw to see if they stay. and as long as the server has 8ish or more people playing in it, they typically dont bother trying to find another server. This works really well as the redirects show very low ping, and they get hit ALOT. Yes it is “ghey”, and cheap but it got the dead 1.6 server back on 2 legs
