# 16-3 Block-Fame The index for Volunteers sales reputation, corresponding to customer purchase activities and sales history. It is different from current reputation level on social media which is based on quantitative measuring of the number of followers/fans, and of comments or content views - which are vulnerable to fraudulent activities like fake followers, liking bots, and etc. Block-Fame as "Proof of Fame" plays an important role when making a profit sharing contract between a supplier and an Volunteers: transparent, standard guide. As it reflects the accumulated activities and token rewards of the Volunteers during the most recent period on DonaBlock, Block-Fame stays always up-to-date. It also requires the participant to earn and maintain DonaBlock Tokens, which increases the level of contribution by the Volunteers to the DonaBlock platform. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
