Useful research signals
Descriptions, repeated photography, inventory specialisms, stated locations, measurements, and distinctive business language can help connect an item with a professional dealer.
The strongest findings are corroborated through more than one independent public source.
What verification should include
A professional report should explain the business identity, provide public contact routes, and cite the evidence supporting the match. Ambiguity should be disclosed rather than hidden.
What responsible research excludes
Responsible research does not involve account intrusion, deceptive contact, credential harvesting, private residential information, or claims that cannot be supported by evidence.
