The Kled app said it pulled its service from Nigeria and blocked local internet protocol addresses after detecting widespread fraudulent data uploads, including black screens, duplicate images and internet-generated pictures.
Kled, a Solana-based app that pays users for uploading data, said it has removed its app from Nigeria and imposed an internet protocol address ban on the region after estimating that 95% of uploads were fraudulent. According to the team, problematic submissions included black screens, duplicate photos and internet-generated images. The move highlights a common challenge for crypto-powered data marketplaces, where token or cash incentives can attract low-quality or manipulated contributions if verification systems are not strong enough.
