People either don't understand how this works or are incredibly dense.
You have the right to play your game. No one is taking the game away from you. Playing online comes with accountability. Something that has been dwindling over the years. Way back some 11 years ago there was this game called EQ. Playing EQ took a LOT of time, more time than anyone should really devote to a game. But that amount of time spent meant that people werent twats. If you were the ENTIRE server would blacklist you and you'd never get a group again. YEARS of your life down the drain. It was fantastic because people weren't asshats because they knew they'd be flushing their time down the drain if they were.
Over time this all started to fade more and more. Being a complete tardcake started to become the norm. People would join games with the sole intention of ruining them because no one could stop it. More and more people decided to join in because if timmy wasn't going to get caught I wasn't either.
Someone decided to take that old fashioned sense of accountability and bring it back to the RTS genre. They made banlist. Now a host could keep track (without a messy stack of tree murdering paper on his desk) of all the douche nozzles that joined his game so he wouldn't have to deal with them. Hosts rejoiced, griefers cried, and people that seem to think this is a case for the ACLU cried foul.
Banlist, the program people have their panties in a bunch over is only a personal banlist for the average joe. The only way to bring a global ban on yourself is to go OUT OF YOUR WAY to do it. There is no magical feature where you can globally ban someone. In fact YOU WILL NEVER globally ban a single person with it, ever. You....will....never. It isn't some bullshit griefing tool, its a local personal banlist. If spooky is calling everyone a bunch of N-words do I really have to justify my never wanting to see him again? Fuck no. He's done.
A global ban with the banlist program only comes from TDA. Which is a private league you sign up for. The rules are here http://forums.dota-allstars.com/index.php?showtopic=276504 the application is here http://forums.dota-allstars.com/index.php?showtopic=277378. You know full well what you're getting into from the second you sign up for it. So you know full well you're going to get globally banned when you fuck up. It's like getting busted for roids in baseball. You went out of your way to do it knowing full well the consequences beforehand. No one made you do it, you signed a contract, you brought it upon yourself with no one to cry to.
Outside of violating TDA rules there is ZERO, nill, zip, 0 way to become globally banned. The people who can make the global bans are a select group of approved hosts who have to justify every single ban with a replay of the game. All bans may be appealed. NO person can be globally banned outside of a TDA game. So, where's the problem?
Once again, this website will go absolutely nowhere so there is zero need to talk about it like it's going to catch on like wildfire. It wont.
