On one hand, it's the complete opposite of seeding and will exhaust seeders' patience and steal bandwidth from people who want to watch it. So that's actually hilarious.

But on the other hand, it does ultimately come off as and inflate demand. It could stretch and artificially boost perceived hype over time. Like if a seeder sees constant downloading of it, or leechers see other leechers after years, they will be empowered in their hype for the thing.

I think the correct thing to do might be to report any torrents you find to the copyright holders and drive spite between consumers and the copyright holders. This may increase direct money spent, but it also acts as a deterrent from the media. And one thing that's really apparent here is that there's all kinds of people who act on all kinds of reasons: morality alone, the shared active goal of draining interest in the media and franchise and jkr herself, only not wanting to give jkr money but still wanting to consume hp, etc.

So, statistically, in order to kill the idea of hp, telling people to simply not consume hp at all isn't enough, and in some cases, may create a taboo or even spite motivation. Shame is a very strong motivator, but clearly, either some people aren't quite getting there, comprehension wise, or don't give enough of a fuck about the effects, or some level of values and combination... Basically it's just not enough on its own to tell people it's wrong and why because people are... Human.

Tldr: If you care about trans people's civil and human rights, just let go of hp. Don't just boycott spending, boycott using at all. I know this is clearly a big ask, but I sincerely think that if-statement holds true.
