What are Spam Scores?
Every time I talk to the SimpleHash team, I always think: 'Wow, those people are true professionals.' That’s why I really like working with them in a nascent industry like Web3 apps.
NFT spam is a growing issue in the digital asset world, where large numbers of low-value NFTs are distributed en masse, often to deceive or overwhelm users. SimpleHash addresses this challenge by implementing a sophisticated spam scoring system, utilizing a variety of signals to assess the legitimacy of NFT collections.
For developers, integrating SimpleHash’s spam scores into their applications is essential to safeguard users from potential scams and to enhance overall user experience by filtering out irrelevant or malicious NFTs. This becomes increasingly important in networks like Polygon and Solana, where high throughput and low costs can exacerbate spam issues.
