Can you link to the problematic pages so I can confirm? I'm browsing the front page of lemmy.sdf.org right now and the first few links I clicked on had nothing blocked. There is only 1 domain connected when viewing your post directly, and 27 domains connected on blahaj (assuming its our emojis) with 0 blocked. What adlists are you using?

Using the uBlock logger, I see the front page of lemmy.sdf.org contains links to images (?) like:
I changed the hash, in case it's sensitive. I have no idea.
When I visit the URL, it doesn't load.
From the URL alone, pictrs might be referring to https://lib.rs/crates/pict-rs. I've seen talk about pict-rs being used as the image backend in Lemmy as found here. When I inspect the thumbnails of posts on lemmy.sdf.org the URLs are in a similar format. I think its picking up links to images on other instances.
I checked my logger and got a red hit for https://startrek.website/pictrs/image/3b51f06d-2714-4fac-8a90-79f5f1397c7d.png?format=webp&thumbnail=96 and while it looks concerning, the column with the rule says /^https?:\/\/[0-9a-z]{5,}\.(digital|website|life|guru|space)\/[a-z0-9]{6,}\//$xhr,3p,from=~127.0.0.1|~bitrix24.life|~ccc.ac|~jacksonchen666.com|~lemmy.world|~localhost|~mempool.space|~scribble.ninja|~scribble.website|~spacepub.space|~traineast.co.uk so it was just a pattern match on a bunch of domain TLDs commonly used for scams or ads. With the recent increase in Lemmy's popularity, server owners are buying up cheap domains that fall within those TLDs and you're likely to be seeing one of those.
Thanks for the detailed explanation!
Could it be one of the communities has dodgy posts that link off to sites ublock doesn't like?
If true, this is a bit disturbing. However, I run uBlock in my browser and don't recall seeing any blocking attempts when on this instance. Do you have any specific details?
See my other reply.
