tronsuser: Thanks for setting me straight on that point. The FAQ has been updated since I did my research, which was when Game Ban was introduced some months ago (the week after the paid mods debacle IIRC).
This is a
partial relief. I'd still like to see the word 'disruptive' defined in some detail. Until then, it doesn't single out those who 'ruin other people's experiences', but anyone the developer doesn't like.
It's not like devs can just go around banning people willy nilly though, not only do they have to be 'approved' to do so, you can report them if you feel it's unjustified
Will Valve review developer requests for banning in any way?
Developers must be approved to use this system, and Valve reserves the right to revoke access to the system if the developer abuses it.
Do players now have to appeal bans by contacting a game developer directly, or can this go through Valve/Steam customer service as well?
Players should first contact the game developer if they wish to appeal a game ban, since the developer has the data describing why the ban occurred. If a player feels the game developer is being unreasonable, he/she should contact Steam Support. If Valve determines a game developer is abusing the ability to apply game bans, Valve can remove the ability for that developer to apply bans in the future.
