I know how you feel, but in the end ;
a.) It's their repeater as well, not just yours
b.) You're not a policeman
c.) Things that you feel strongly about isn't any one elses' problem but your own.
d.) unmet expectations will suck your life dry if you let it
You could ditch it all and use D-star, then you could see all the callsigns.. for.. some.. reason.. or you could just not worry about it.
