It doesn't matter what time it is, if you're breaking the rules and in turn ruining the fun for other players, you'll be punished. It may have been 3:00 AM where you are, but it was only 12:00 AM where I am, and for some players it was as early as 9:00 PM.
I get what you're saying though, watching horse archers spend more than half the round riding away from the enemy team is very irritating. But as long as people are still actively shooting at each other, the rules aren't being broken. There's a huge difference between trying to save your multiplier and drawing the round out and actively delaying the round by basically AFKing when you're the last two people alive.
I do my best to treat everybody as equals, I'm sorry if you're upset by the way I handled the situation, I wasn't fully up to date at first, so when the ban thread came up it gave me more info to work with.
Ultimately, it's important to remember that not everybody has fun the same way you do. You may have seen it as late night shenanigans, but to the others it could have been prime time delaying.
Not that arty was involved whatsoever, but friends have been banned based on simple 'Q' chat spam. If using a vocal, non-combat effective spam is equatable to hourly/daily/monthly ban then we either need to rethink functions or rethink Admin applicants.
I've never seen anybody get banned for 'Q' chat spam, but I'd agree with you that it's over the top. We have a mute and a kick function for a reason.
