I try to not spoil stuff
If something gets spoiled for me, if it is interesting for me, I usually go and play game to spoiler point or watch entire show. If it`s not interesting, I tend to forget it.
I think it also matters how it was leaked. Was it entire episode or just random scene out of context? I think I still would rewatch spoiled episode, just to get things in context of previous episodes.
Overall, getting spoiled usually makes me interested in something
