Canonical was giving free CDs when I was a teen and it looked cool. Later versions of Unity DE were so good, I liked older Ubuntu so much. Now I run it on older devices to give them some life back

Some of the apps allow blocking of instances, I use Sync For Lemmy and I blocked pornlemmy and lemmynsfw and I don’t see porn anymore for the most part, there are still some stray nsfw communities on other instances but I rarely see any of their content
