if someone opened the boost section and saw the server it will not show to him the server name or the ip how is he gonna know this boost belong to wich server
that's not how the boost work
the websites that offers boost service has special version of cracked cs 1.6 in their website
and players download this cs 1.6 because it's free ofc, so when someone boost server, it appears in this version server list that's why we get some players after boosting because they find pg in their server list with the other boosted servers.
no one would search for servers in boost list because they already have it in their server list in game that's why hiding server information wont affect boosting, but it would be better to open it so we can see who boosted.
