False positive: mastodon.cloud returns "found" for all usernames — instance appears decommissioned

Additional info

mastodon.cloud returns "Found" for all tested usernames.

Usernames tested (all returned "Found"):

• hy_its_ritesh_yt
• asdkfjasldkfjqwerty12345xyz (deliberately invented, cannot exist anywhere)
• ThoughtGreedy3596
• MostAd8747

Evidence: Visiting a reported profile URL directly (e.g. mastodon.cloud/@asdkfjasldkfjqwerty12345xyz) redirects to a hosting provider's shutdown notice reading: "We currently do not provide services in your area," with a service code (093) and support email ([email protected]). This page appears identical regardless of username, which would explain a 100% false-positive rate.

Cause: The instance appears to be discontinued, decommissioned, or strictly region-restricted.

Fix: Rather than adjusting detection logic, completely removing mastodon.cloud from data.json is likely the best solution — since there is no username for which this domain currently resolves to real content, no errorType value could correctly distinguish "found" from "not found" here.

Checked: confirmed mastodon.cloud is not currently listed in false_positive_exclusions.txt.
