5 mins? I remember there being just 3 people on the gg server and I had to kick one of them as he constantly rtv'ed no matter what map it was, and when there were only 3 people on it allowed 1 person to make the vote work! He did it 9 times over the course of a few minutes before I got fed up and kicked him (warned him plenty too)
I don't mind rtv to a certain extent, and being an admin I don't rtv unless the majority want a map change (in which case rtv would enable anyway) or say 7 out of 16 players want it changed. but when it get's to the point where people rtv at the start of every single map... I feel that they shouldn't have the right at those times tbh
