Most valve games actually already temporarily block incoming from your IP if you hit them too much from the Server Browser. The "View Info" for a server, you can hit the refresh if it's full so you can see if theres a slot available and the scores. If you mash that more than 10 times in like half a minute, it "Server Stopped Responding" for a while like 1 to 2 minutes on a cooldown. That /might/ be coded clientside though. I do know it ducks waves of info requests though. Using outside programs just pinging not sure if it will stop it though.
