There are many topics people discuss that are problematic. Forget piracy. What about people from authoritarian regimes, people from countries that are in danger to fall to authoritarians, even if they haven't yet. Anything from years ago could become problematic if the wrong government gets into power.
Making jokes about God is no deal under some regimes, it's blasphemy in others.
Drugs are a problem in a lot of countries, and a literal death sentence in some.
Making fun of a fringe politician is nothing when they are not in power, but becomes a problem if they get into power.
I am sure Reddit gives some data in cases of actual danger, which is fair. But if they start to hand out data for something minor like piracy, it's going to be a problem for discussion on the discussion plattform.
Whatever. It's not really admissable. People talk about tons of things that they don't actually do. For example, I talked today on teams about deleting a problematic app from our vcenter just so we didn't have to deal with a compatible issue. Didn't actually do it.
