There is such a thing as a healthy level of avoidance towards topics that make you feel unwell or even in a real-life clinical definition of the term trigger you - but you are the one to actively take care of what you view. Because these people do not even know you so no, you have no right to ask them to take care of you. Move on. Tagging is a nicety but not an obligation.
Unfollow and block when you need to. Circling back to number 1, you are responsible for curating your own experience. Remember at the end of the day, there are actual living, breathing people behind each screen name. The problem isn't so much that shows are shorter, it's that they can't choose how long they want to be to tell the story they have in mind.
I've seen plenty of shows that were eps per season and absolutely had no idea what to do with that run time. I've seen 24 episode shows that should've been 12 episodes. Hell, I've seen 24 episode shows that should've been 6 episodes.
One of my favorite shows of all time, Bomberman Jetters , is two 26 episode seasons. I love the core plot, but so many of the side episodes are notably worse to the point that you're really just sitting there waiting for the show to get good again, which wouldn't have been an issue if the show was two seasons of 13 episodes instead.
On the other hand, 12 episodes is plenty of time for any competent writer to explore an entire cast. That's four hours of time on the short end and ten to twelve hours on the longer Netflix-y end. However, if the writer is good and the cast is large, then 12 eps might not be enough because their world is too good, but nobody does 24 episode stories anymore for syndication.
