Here's the answer for me, at least: I believe this thread should always be useful as a tool for people who are just casually interested in anime/the current season of anime. There are always people new to the medium for whom this could be their first season that they're following shows as they air. I feel like it's my duty to give these people fair warning of the kind of content they could be experiencing in their shows. It's very easy to become desensitized to the problematic elements present in some (but not all) anime productions, but I think it's important to try and come at an anime with a fresh perspective to help better serve this audience.
The alternative is that someone hears the glowing praise around, say, Made in the Abyss, and as a result they decide to check out the show for themselves. They will then surely run into the objectionable material and wonder why no-one in the thread even thought it was worth mentioning? They'd have to assume we're just a bunch of very insular anime fans who aren't bothered by scenes which are clearly objectionable. I'd rather try and prevent such a thing from occurring.
Now, that's just my own take on the matter and I certainly don't see it as anyone else's responsibility to point out these issues when they comment on a show. But I feel the need to flag up these things, especially when it occurs in relation to a series that could have some mainstream appeal.
