do you use myanimelist?

Yes, but I'm sometimes uncomfortable with the community there tbh. It can become very toxic and there are especially quite many incely guys, who hate and bash on women and queer people, it's not funny.
But I still use it, because it's so far the best site I know to list anime and I met some really nice people there as well.

Anilist is less toxic I think, but the community isn't so active and it takes a while to load the lists and covers sometimes.

I forget about Anime Planet most of the time, but I could use this as back up as well.

I was using it sometimes, but I am more used to anidb.net :)

I use it mostly just to track the anime i've seen and am waiting etc.

Not really

I use it often, it's really very practical

yeah, I use mal. one of the webtoon adapted into kdrama and this is how I recently started watching kdrama. 

Yes I do! 

Not yet :P
