If I was logged into several instances at once in the client and seeing the composite feed and then could choose instance when replying or posting (with some set default, like from: field in e-mail clients) lemmy.world could ban piracy all it wants and it'd still be in my feed without me having to leave it or change instances.
I am not asking you to stop using lemmy.world. It’s their instance, they can do whatever they want. I was replying to the above comment that the Instance owners don’t want any chance of getting sued. As long as they have an Instance in the Fediverse, there will always be a chance of getting sued.
But it is perfectly normal to try to lower the risk of getting sued, even if the chance will never be zero.
