Sorry, I don’t use wefwef. In the main browser, you can navigate to the community and the “block” button is right below the “subscribe” option.

Near as I can tell, there are certain communities that have a “rule” that every time you browse that community, you must post something before you leave. This leads to a lot of low effort shitposting that I guess some people find fun but I just blocked those communities so my /All feed wasn’t cluttered.

I feel like there’s a lot more to this than “pay it twice”. If you’re talking purely in dollars, then you’ll want to consider maintenance and upkeep over the expected lifetime of the object and compare that to alternatives. Additionally, everything has an opportunity cost because no resource is limitless and you could have allocated it elsewhere. Finally, emotional and other intangible benefits are something that most people have a very difficult time quantifying.

If you want to say “consider more than just the purchase price” then I’m with you.
