Better moderation.
Absolutely
global moderators
Absolutely not. I wouldn't trust any person in this community with that power. I'm friendly with the <@> people. I admin on izzy's server, I've talked a little with mat^2, hompy, Sham, BOOYO, Tank, Stack, TGM, etc
I wouldn't trust them not to make mistakes, and given the status of moderation now, I doubt that would even be enough people. And if there's anything I trust less than people I moderately trust - it's the people they moderately trust.
Take Exor getting 'fired' from adminning on GH. People aren't reliable and this plan requires people.
Hell, I trust myself pretty well and I wouldn't trust myself not to get mad one day and global banning some guy who wouldn't stop annoying me.
An idea I would accept a little more easily:
an account system with 'flags'

But the flags are by
admin accountSo I ban Grieferdude for major griefing and ignoring warnings and label him a T3 Griefer.
He is added to my list on ace-spades.com, which server owners can
opt-in to use.
So say I run a server and I subscribe to aloha's list, GH's list, ace-spades's forum list, and StackOverflow's list.
I could even set thresholds: don't let in any T3 offenders from those lists, don't let anyone with a total of 4 points in, ignore any T1 infractions, but disable building on any T2 Griefing offenders.
For instance, I would subscribe to all those lists but only auto-ban T3 aimbot offenders and ignore all the rest.
I have absolutely no idea how feasible (if at all) this is. Obviously it would have to be tied into vanilla servers, pyspades, the client, the website and would require a lot of work, but I think it's a good idea.
