I use Lemmy on desktop browser as I did with Reddit. An interesting note is my uBlock Origin extension shows a counter in the address bar for blocks of any kind. It did a pretty good job of blocking ads on Reddit and I would see pretty big numbers in the counter.

On Lemmy the counter never trips. I don't think there's any web site I visit regularly that doesn't trip at least a few counts. Since my uBO extension is set up to block all kinds of undesirable stuff, not just ads, it demonstrates how clean the coding is for Lemmy.
