For GNW there is the white list
For info let's face it any info we can give u can look up on form
So I say this is a problem in only new servers where the more experienced players can get a advantage and can share the advantage with the noobs(advantage early game = info) I mean let us take s1 as a eg. Any one who plays on s1 and has reached over 80 ish (of 80ish on other servers counts too) will be/she need the info u can give? I think not.

And besides it is not possible too harm a group unless that person is higher than any even then he/she can only mess up.the use of funds that is what is up ed first and summon catching time.
So yes I don't get why so many people complain.
