Maybe characters do communicate using magic?..
Let me see if I understand. Someone DID what to who?.. As far as I know,
The idea of a thieves guild and such... the problem there... is that you can't force ANYTHING on another player. Just ask those that have tried to play a bad/evil character or tried to set up a blockade... People would likely be much less rude if they could be put in their place without having to "accept" the consequences first.
So, if no one can really steal, kill, push or do any, then why bother playing a baddie? The only way is via RP, right?.. well, this is a RP game, so RP your goodies and baddies. It's the only thing you can really do. And if for some reason, you end up in DR, it's your fault for accepting a challenge, having auto accept on or being at the wrong place. That's the way we all want it, right?.
I used to be part of a guild like the one described. It's the only guild I've been in and since then, I have found no reason to get into another one (or the same). Why?.. Well, some bad connection in my brain states that if there is no chance of doing it, then why bother?.. therefore, being in a baddie guild and RP does not compute very well in my brain.
Social behavior is no crap. Communication between social entities is inverse in complexity to the size of the parties. For example, two individuals can talk very deeply about any topic for a long period of time. Add some couples and you end up with two groups who don't really add much depth to the topic. Add some dozens and they just understand yes, no, demo, repu, black, white, kill, die and so on. The larger the group, the simpler the concepts.
Guess why is it that RPing a blockade is so easy when it starts and so tangled when it's ruined? Careful! the only way for a single individual to deal with large groups is in a conference, speech or alike. It can not be a conversation. and this is why GM's have greater chances of success when doing an event. They can impose the conditions of the communication and impart discipline on the monkeys.
The characters in the game recognized that guild as a baddie for it's reputation. And it still goes pretty much the same way. Ask yourselves, what kind of identity this and other guilds had today if it wasn't for their glorious past? I mean, some recent player could very well oversee the character of a guild and some could say to him "Be careful, those are from ------- guild, they're badaches!" maybe he'd say: "lolz wha?.. they can't do s*** to me. I'm the omnivoroplus...ultra...mega..." and blah, blah, blah.
And you could reply now in this thread: "..but my guild is still the ---- blah, blah blah" NO! it's the bandit who gives the cop it's shoulder stripes. It's the rule.
What if I asked you to prove your skills accordingly to your RP? (specially when playing the omnicapable)... well, I could ask the same to a guild. And?
There is currently one single way. RP.
