Well I never thought I'd post a white list, but here goes.
Bear in mind, friends of mine, (rhyme not intended) I am naming people of white list nature that I see as being very helpful people. Just because you don't help, doesn't make you a bad person or any less my friend, I am just not recommending you to others is all lol. Just because you're not on the white list doesn't mean you're on the black list. As Avoklex pointed out, I am very honest.
Vayde - I will probably never meet a player in this game that can accomplish so much yet do so much selfless acts. She is always willing to help people she knows and even willing to help people that shout. If she is busy when you ask, try to remember that she gets a lot served on her plate, so try to ask her ahead of time and remember she wants to level up RNG too.
Eudardm - This guy is very very nice. It's almost unbelievable. When you meet him you immediately think there's a catch. He is, at the very best, a person who will listen when you need someone to vent.
Shuvo - This guy is ultra cool. He's very friendly and risks a lot to help his friends. We started off together at TGS, but when it fell, me and him remained friends.
Scuba - This guy rules. If you want to find someone to trust, Scuba is the best. Don't cross him or he'll MPK you of course lol. Scuba is a great person, arguably one of the best players on the server and I'm glad to be his friend. If you want advice on farming or gil-making, he's very nice and informative. He will even help you camp an NM for an expensive drop without benefit to himself. That's about as nice as a person can get.
Navigator - This galka THF rules. It takes a lot of character to help a person that your LS doesn't like. Navigator was willing to do that for me. Even though his LS doesn't like me, he still didn't pass me up as a friend and that's a toast for him.
Fobschoolboy - The prince rules. He's the best NIN on the server hands down and he rules as an LS leader (even though he doesn't call himself the leader lol). If you ask him ahead of time, he's willing to help but even if he doesn't, he doesn't lie about it, he's 100% honest about whether or not he'll help.
Jomachines - This guy is an inspiration. He's the best WAR on the server hands down, and if I had to, I would join other servers just to vouch for him as being the best WAR all-server. He is a great individual too and if you're aspiring to be a full on WAR, he's 100% honest about the pro's and con's of leveling WAR versus other tank jobs or damage jobs.
Zerolex - This guy might come off as quiet but if you actually talk to him and get to know him, he's a very good friend, willing to help you out. He's also very informative and provides a realistic opinion on high level aspects. He doesn't get caught up in a lot of the political BS that follows people when they turn the corner at 70.
Animas - Ask her for help and you'll find out for yourself why I white list her. She helps, and that's exactly why.
Haltehtar and Iroo - I put them both in the same listing because I met them both the same way. I met them in an LS that I was "removed" from, but yet they still remain friends with me and they're always willing to help. Hal is really cool, really nice and if he's free, he'll help you. He's the only person I know 70+ that doesn't act like he's ahead of everyone else. When he helps, he 100% helps, he doesn't go unless he's willing to go all the way. Iroo is probably the most outgoing mage on the server. Every time I have asked her for help, and even times that I didn't ask her for help, she would always be willing. I don't even know how she got to level 71 to be honest, all I see her do is farm and help people. These two guys are great players and you could find one by contacting the other if you needed XD
Buddweiser - I know putting him on the same list as Vayde might be considered contradictive, but how nice a person is and how skillful they are, are two different characteristics. Buddweiser does like to help his friends a lot, despite whatever questionable actions he might've taken in other times.
Calceous - This guy has guts. He's the only 70+ player that I've met that shrugs death like it's a bad serving of toast or something lol. He's a really upbeat stand up guy, and even though he's not a PLD, I've seen him put his **** on the line to save the day.
Darkon - Another player that disregards linkshell political warfare when it comes to friendship. He's a very helpful person and a very nice player too. High skill and willing to do good things for others.
Trunks - Jason from Power Rangers rules, 'nuff said. Very friendly PLD, very high skill and goes that extra length for his friends.
To everyone else on my friend list, I'm not exposing you here because I know that you do help friends, but I wouldn't want to regard you as something that does something you don't. I am grateful for all you have done for me and you are definitely on my white list. These are just players I recommend be noted for being on Sylph's white list.
