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", ...).
This is what you get when most people do that.
Never give "your guy" powers that you don't want the "other guy" to have.
Because the powers you give to Obama... will end up with Trump - and vice versa.
