@TracyRussellBlack I think you can just not follow any Tumblr accounts and you’re good. And I doubt people who do follow Tumblr accounts will boost ads. So it’s probably not a big issue if they do.
Mastodon is the best way to keep up with what's happening.
Follow anyone across the fediverse and see it all in chronological order. No algorithms, ads, or clickbait in sight.
