Theres a problem though, many times the 1 spammers don't intentionally do it. The mapvote comes up at a random time during gameplay and as you are switching to your primary, you hit 1.. So you're going to have people slayed because they wanted to switch guns?
here is a solution.
Deal with it.
if people complain about that map that was voted for, admins do your job, create a new vote.
all i see here is an attempt to escape even more responsibility as an admin.
just make
1 = -
2 = 1
3 = 2
4 = 3
etc...
slay sounds good too.
Admin Rule #4: Make your own map votes, don't leave it up to the random voter.
The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts.
