Hello! Subfinder is only a passive DNS tool, and thus uses the data sources you specify, and thus may return active domains that are marked as active in those sources but aren't actually.

Most of the time, you'll want to pass those results through DNSx or HTTPx to confirm if they are still valid records and responding to requests. Learn more about those projects here: https://nux.gg/dnsx & https://nux.gg/httpx
