What happened to the URL on file for Appen?

URL unreachable The URL on file (https://swapper-ai.com) did not respond across three consecutive checks; the streak completed on 2026-09-01.

This reports what that URL did, not a claim that Appen itself is gone: the address on file does not confidently match Appen's own domain, so if it turns out to be a marketplace or listing page rather than Appen's own site, this observation is still accurate about the URL, just not about the product. See the methodology for how the match is made.
