When I search for “PieFed” on DuckDuckGo, I get the expected results. https://join.piefed.social/ is the first one, of course.
On Google, the first result leads to a 403, and the second one is a Reddit discussion. https://join.piefed.social/ is nowhere to be seen.
It’s not really the point of my post. This site isn’t officially related to PieFed and shouldn’t be the first result of a search engine.
Fair, though Rimu already addressed that (his anti-AI scraping countermeasures likely caused that), so I was offering the additional fact that the site worked for me rather than generating a 403 error as it did for you, and a way to further test why that error came about.
