"Friendiest" meaning: with the fewest haters, trolls, spammers, and other negative people.
Idk if this list makes any sense so... Add answers if you feel something is missing.
I didn't add Twitter and Facebook to the list because I figured it would be harder to measure the "friendliness" for those two. But you're free to add them if you want to! :)

I'm not familiar with most of the list, but between YouTube and fanpop, I guess fanpop - so far anyway, I have seen quite a bit of hate on YouTube.

Everyone on Fanpop is freindly!! except for those one or two people. :D

Fanpop is really quite friendly. YouTube most definitely is not!

:)

Tumblr is WAY too aggravating sometimes!

Fanpop I think.

Though I love talking with my subscribers on Youtube, they're always nice. Overall Youtube community can be quite bad, but the people who comment on my vids are always lovely :)
And Deviantart is quite a nice bunch too ^^

tumblr ruined my life

> YouTube: haters, troll, ass holes
> Tumblr: comes close

Fanpop 4 sure cuz I actually back out of DA cuz of people ahum!!! DisneyWiz she's a complete and total jerk anyone that likes her is blind she's a bully

Fanpop has less trolls. but the other ones are with most trolls

Fanpop - the thing is that i loged on on fanpop (i said on 2 X) because they have less cussing. and less trolls as well

Facebook - their are more than 1 troll. because Facebook has more cussing. and much lately. they have lots of banning on their as well, my little sister has a Facebook account


YouTube - they put mean comments on videos. i sometimes be on YouTube. i also have A YouTube account as well. but YouTube is not quiet and peaceful. they have LOTS of cussing to do on their

Tumblr - well. its kinda ok. but same thing.


i will edit it the next day. kidding with you.

then Fanpop.

Anything but Fanpop and Fanfiction 0_0

Full audit:

YT: My god, Monstercat comments.
(See Noisestorm - Airwaves)

Tumblr: Dunno, but I saw a hater by the name of Fusion Bio-Former.

DA: Almost as great, after some lurking.

FF:
Pretty good, but reviewers are rarely good, with little or no knowledge of English IMO.
And haters, too.
(i was one of them)

Feisbuks:
"ZUCKERBURG!"
(Patrick Star shouting the "name" @ Sailor Mouth)
Same as above.

4chan:
The heart of the Internet is a no-man's land, no-holds-barred place.

Rest of the boards are kewl tho

Youtube has the worst community ever. I can't even say how many times I've been called 'dumbass' 'bitch' 'ugly' 'retard' for my opinions. I just stopped commenting on YT all together. The people there are just really rude for the most part.

Tumblr is alright. I mean there are really amazing people there but then there are real jerks too. Like the tumblr Once fandom has so many 'anti-blogs' and then there is the whole 'white cis males suck!!!1!!' thing. I even recall one of my Once Upon A Time polls getting linked on tumblr; the Swan Queen fandom made over 100 accounts just to vote on the one silly poll and then left. I felt like it was over the top and unnecessary how many spam accounts were made (like I said over 100 in a day alone!) and over such a trival and insignificant poll. But like I said there are some nice people there as well. Not nearly as bad as YT and I've had some people say really nice things to me.

Fanfiction is also amazing; typically people are super nice to me on reviews and the criticism I've received so far has always been constructive and well-meant. I also have a handful of users who review most all of my fics, they really do make me feel good abour my righting.

Deviantart is also pretty nice. Not many people view my page, but those who have left me kind comments and such. And when commenting about others' works I often find myself in a friendly conversation.

I only talk to people I know personally on Facebook so I can't say much there.

I don't really use 4chan so I can't judge.

Fanpop though is by far my favorite. I've been here for about 5 or 6 years now. Naturally I've had my share of run ins with trolls (but I could care less about them, some are even fun when not making personal attacks) and a very rare user or two who was just unfriendly (I won't mention names there but one got banned and two of them are no longer active). But generally I like everyone here. I've met a lot of people I enjoy talking to (espcially on the Winx spot, everyone is super nice there--they have made me Christmas and birthday gifts as well as supported me when my dog aunt and grandmother passed away). I remember being in 'the Biggerstaff Family' we were kind of a role-play family that loved Harry Potter. There was fun role-play on the Bellatrix spot. And after a rocky(ish) start on the Once spot I've found various friends there. So overall, people here are pretty nice.
