Well I was wrong, I checked my network panel and it’s definitely just thumbnails that it’s fetching, I’m dumb I thought that only domains that served scripts ended up in the uBO matrix panel, I did a test and it does that with any third party content instead, static or not :p

From the community main page you tap the three dots top right of the screen and choose “block community”.

It’s definitely not only static content tho, I block third party scripts with uBO and it shows other instances domains in the blocked list.

Edit: I was mistaken, it’s just images
