I can kinda see it happening on mainstream internet, on YouTube etc. with witless non-nerds but I’m surprised to see it in places that inherently require one to be a tiny bit internet savvy, like Lemmy. I get that getting a bot spam the same message isn’t exactly resource intensive but i still wonder if the cost-effort-return ratio is worth it.
You gotta block what you don’t wanna see or choose an instance that has similar values to you as they’ll be defederated from a lot of shit you don’t wanna see.
