I'm a new member to MAL, even though I've been reading reviews on this site for a few years. It never occurred to me to make an account until now :D It's nice to have a place for my loooong anime list. (80 something series as of today, I think).
I dislike long series, unless the story is something magnificent.
I dislike ecchi.
Other than those two things, I'm pretty open-minded when it comes to anime.
Honestly, if someone writes bad reviews for almost every series they watch, I'm not sure why they would continue to watch anime at all.
