i dont know about ping but i was a frequent player of DODsource and as long as its under 100ping i have no problem keeping atleast a 1:1 kill:death ratio. its not something i complain about, i know other player in the server should be getting similar thing. also i find it ridiculous to auto ban people with low ping because i beleive players with low ping should not slow down a server. ping isnt the first thing i look at when i join a server, usually maps. there's always that one server that have one permanent map, and a bundle of players that play there everyday for 6 hours and they've been there for over a year. and its not even capture the flag, just mindless shooting.
its hard to find a good server. with fps too much annoying and disrespectful kids between 7 an 40 years old, hard to find a server with cool people and adults, and at the sametime doesnt have ridiculous rules like "omg" is a swear word. these people have their heads too much up the fps and lost a sense of normality.
one time i was banned from a server because i headshot this pretentious sniper who is a mod who think he is too good and thought i cheated. which fine with me, plenty other servers.
