I also hate spoilers, but sometimes I just get swept in and end up reading some, and it pisses me off.
I used to exclusively read spoilers for the shows I watched, but I started realising it ruined a lot of the episodes. Things like the reveal of The Master in Doctor Who's Utopia and various things in Stargate got spoiled and it ruined it for me.
Since then, I try to stay completely spoiler free, and that's the way to go. Enjoyment is high!
