@foolI have this option on Fedilab 2.x (I haven't gone to 3.x), which I turned off to stop accidentally downloading everything. I don't know about 3.x though?
Maybe @apps can shed more light?
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.
