Is it possible to add an ignore list of say maximum 10 users so that negative rep from them are not counted ?
I don't think that is possible. This is a community so all have equal rights. And that includes the right to give a green, grey or red rep for all the posts here in DP.That won't be taken away just because someone wants to ignore them.
Ignore them! It's nothing at all,no one is perfect,of course there are some people who like you while some don't!Take it easy,dude!
There are a good number of people currently at this forum who don't have rep power You can't take away anybody's right to express his feelings, but the mods will take appropriate action if they find that you are being rep targetted.
True... But I think someone can give an infraction for rep abuse. Can mods do that or is it just shawn that can give that kind of infraction?
