Lurker

A lurker is someone who is watching or observing, but they are not participating or interacting. It's like when you're at a party and you're too shy to talk or play with the other kids, so you just watch them having fun from the corner. In the online world, a lurker is someone who is reading posts, watching videos, or looking at pictures, but they're not leaving comments or likes or sharing anything themselves. It's like they're a secret spy watching everything from a distance!
