I usually don't mind spoilers that much and sometimes I even search some of them up myself to learn more about the work because just the premise doesn't give me enough information. Like, the most important part of a work to me are the themes (in the sense of the message etc not the basic premise) and you usually can't tell what these are and how they resolve (not as in what happens literally in the story to resolve them, but more like what the conclusion of the message is, like what the work is saying about the basic theme - endorsing it? Criticising it? etc) until you know enough of the story. I want to know if I will like the theme because that's the heart of a story, as well as the basic direction the story and characters are taken. I'm also fine with not knowing, but knowing allows for me to be more sure that this is something that will appeal to me.
Regardless, spoilers don't usually ruin the experience for me because I don't need to be surprised in order to enjoy a work, and I usually can still be surprised even if I know what happens because I still don't know how it will be executed until I actually experience the work firsthand. Waiting in anticipation to see how they will execute something that I know will happen has its own excitement and enjoyment to it. Either way, the best works hold up regardless of if you know what will happen or not and shouldn't rely on just trying to shock the audience (imo) - which is why replaying/rewatching should be fun as well (which playing knowing the spoilers is a similar experience to) because it's a fresh experience seeing all the events with the knowledge of what will happen and how it will end. It lets me appreciate the craft of the story more deeply, like foreshadowing etc. I really like just looking at a work in its entirety to see its craft and structure and the intent of every choice the writer made (which I can tell more easily if I know what the ultimate end goal and themes of the work are, through knowing what happens overall) so it ends up still being a fun experience.
At the same time, I understand the appeal of experiencing a work without any spoilers so it's not like I always go out of my way to search up things - that's usually only if I feel like I don't have enough information about the story to see if it appeals to me. It's just that if I do get spoiled, I don't mind that much. And if I do search things up, usually all I want to know are things to do with the story (specifically the themes, not necessarily the fine details about the literal events that happen, but it's also hard to find information specifically on themes because people don't tend to talk about that so I usually have no choice but to learn about enough of the story to extrapolate what I think is the final theme and its resolution). For otome for instance, I usually will still avoid looking at CGs because that's part of how they execute what happens (which is what I am anticipating), when all I would want to know is the information of what happens.
