There's something i have noticed over time on this platform which i need clarification about. Sometimes, i notice that only few eyes have read through a post and the number of upvotes are much. How possible is this? Are the number of upvotes on a post not dependent on the number of viewers? In the image here, there are 32upvotes but only 9viewers. Please, i need an explanation. Thank you!
