It is federated

Pinterest is becoming garbage day by day. Advertisements and every day “Your pin has been removed for rule violation”.

Was there recently a push towards stricter rules?

My experience with Pintrest is entirely based around looking for images on Google and getting blocked by a login window.

My irezumi motives collection is dissapearing day by day, and oil painting tutorials too because occasional nudity, but ads for weapons, some things i cannot describe and religious propaganda? Overflowing.

Pixelfed is sadly more oriented to photo sharing. Never heard of kimis, i guess its time to migrate or just forget about it.

I wanted to have it blocked from the results too, because it plagues the image search.

Its basically a pin wall, where you can organise pins (images) into collections. They had a good algo that recommended similar things for an existing collection.

I used it to look at how other people are painting their miniatures, to search for short painting tips and so on.

Like skele_tron said, I find it useful for finding images similar to existing boards/images. It's like Instagram's explore page, but you can look at an explore page specific to one board or one post. I haven't been on Instagram in a while, but I think the saved posts feature didn't have the ability to suggest (visually) similar posts there.

You can also save images in Pinterest, which I couldn't do in Instagram. I draw sometimes, so it's really nice to be able to download a picture and zoom in on it and have it stay that way.

On Instagram, if you like a post (subject matter, art style, mood) you just have to hope the same creator posts something similar. On Pinterest, you can scroll down below a post and it automatically gives you visually similar pretty images, by anyone.
