How do you manage your whitelist [GA included; ended]

I whitelist people who are funny or useful, (<----often train makers) or who ask without being douchey, plus everyone who I won a game from. once added everyone in someone else's whitelist giveaway that I won, cause I felt guilty. I have no idea how to tell whose whitelist or blacklist I am on, so I don't ask for reciprocation, but if I find myself adding people whose whitelist i make just to be polite.

I whitelist for a variety of reasons. Being friendly, having several conversations via chat and becoming friends, being a great contributor to the community (whether it's in the forums, giveaways, or both) etc. I have people in my whitelist who have 0 giveaways created but who are incredibly friendly and simply do not have the means to create giveaways. It makes me happy to add them to mine and be able to share some love. :)

i rarely whitelist everyone.
unless they give games so much~

I whitelisted some people from K whiteliste group. Other than that... Some active user, I guess.

I whitelist people who help other users :D and blacklist the bad people who make a destructive comment >:D
