All should be in a good balance. It dont makes sense when someone plays 50 tel-games in a season but 10 times against the same player. Barcelona dont play against Getafe 10 times in a season too (in dub-c words).
So, if I ask for tel, and someone agree but I already played against him many games, I can say "no", in my opinion this aint avoiding.
And this: Nice wheat snp has a ignore-option. So I'm using this and ignore all spammers and bad behaviour people. Some tus-members are involved too. If such a person is calling my request with a "yes", I coulnt read it. There is no rule that I cant ignore people in #ag.
In the end: Keep a good balance in a season and you dont have to feel urself bad. And to avoid some **** isnt a crime too. Imo.
