Well, speaking as someone with, as far as I know, no legal way of watching the show when it airs (no TV,) I would like it if we just made it a policy to cut spoilers, regardless of how old the episode is, as they sometimes do in fandoms where the show's been off the air for a long time but new people are still coming in. Icons are okay.
Practically, this is a bit much to ask, so I'm prepared to suck it up and take spoilers after a few weeks. I'm not hugely bothered by them, generally -- it's just more fun without. (Kaito Nakamura's power is the one thing I care about not being spoiled for, and I'm doomed there.)
