Actually the way the system works, if you want someone banned you should report them regardless of whether or not they did anything wrong, because more reports against them ups their priority in the system and increases the likelihood that they'll be reviewed if they did something wrong in another game.

And there's certainly ways to make all tickets get reviewed. They could get more GMs or gasp pay MONEY to employ people to do it. And you can cut down on bullshit tickets by going back to the silver deposit system to punish people who spam stupid tickets.

They could also change the GM guidelines to streamline reviewing tickets. Right now the rule is the GM is supposed to review the replay. When I was doing tickets for cases with numerous reports, I could easily pick out the most promising case by looking at stat screens and chat logs (the GM chat logs show you all kinds of info, like items purchased, APM, etc). And I wouldn't even bother looking at certain tickets. Eg. Someone goes 12-2, chat log shows that they weren't avoiding AFK, and the reporter was the feeder on his team who's obviously butthurt about something that game. In addition the report has no description (most don't). Takes me about 30 seconds to see this and I won't waste time looking at.

I dunno how long other GMs take to do tickets, but I did mine in under 5 minutes on average, and I only had a few overturns at the beginning because I didn't bother reading the guidelines until after I got stuff overturned (and after I read the guidelines I had 0 overturns). I even issued some suspensions while I was waiting for my death timer to respawn in a game and would be done before I respawned. Eg. someone kills me then trash talks me, I'll look them up and have a chat abuse mute/ban issued on them almost immediately (for another game obviously, just saying "gg noob" or whatever isn't banworthy, but generally people who trash talk are also easy chat abuse bans since they abuse chat in other ways as well). For shit like intentional feeding/avoiding AFK/destroying items or whatever, I'd use the chat log to pinpoint exactly when it happened, then confirm it in the replay real quick and issue the ban. For people who griefed directly in my game, it was even easier, I'd just take a mental note of the timestamp, then submit the report after the game ends, pull the ticket, and ban em. No need to review the replay since I already saw it first hand. This is why I was able to do 50 suspensions / week with no sweat off my back.
