Proof of Usefulness Score
Lab Mode

The submission for SellOsphere presents significant red flags, primarily the claim that 'most people have used my product,' which is factually impossible for a boutique B2B lead generation agency. Additionally, the submission lists the name 'DeepBlade' (likely a user handle) while describing SellOsphere, suggesting a low-effort or automated entry. No verifiable digital footprint, team details, or revenue data were provided to substantiate the existence of the business since 2015. The 'audience reach' claim of 'everyone' further degrades credibility.
