I don’t really get the Pinterest hate, but from what I understand it’s because their walled garden content came up in web search results. Anyway I’ve been using their app for over a decade. It’s the best place on the internet to explore visual art. The content is manually curated by users and the feed/recommendation algorithms are super good. It’s got very few and inoffensive ads too. The only issue with it is now the occasional AI content.
This is the most common blocked site on ublacklist lists and kagi and probably it is also on many of the common dns blocklist.
