https://search.marginalia.nu/ is a great little search engine for research. It favors results that would most likely be buried in the larger engines, excellent for finding lesser known sources.
Also the “random” button is a lot of fun, and fairly nostalgic if you remember the late 90s-early 00s web. Lots of geocities style personal websites still out there apparently.
Just chiming in to say Kbin does appear to have a block feature - it’s the little circle with a slash through it next to the “subscribe” or “follow” button for a magazine/user/instance. I only found it recently, so spreading the knowledge around.
