Even better would be if there were user-configurable "lists", whereby you could decide upfront what you want / don't want to see (like many sites do right now with NSFW content) - the default filter would be very "protective" (no porn, no violence, no gore, no hate speech) but users could turn off any or all of these "filters". The next step is the addition of user-curated "lists" / "filters" (e.g. "no democrats", "no republicans", "no vegans", "no dog lovers", ...).
An endless volume of tweets under every charged trending topic violates these rules, which are being surfaced and promoted by the platform. And it enables mob mentality like nothing we've seen before.
Moderation is mostly just theater, especially as long as the platform itself is quite literally encouraging the core behavior.
