YouTube has stopped allowing channels to hide their subscriber count as part of a larger effort to combat creator impersonation across the platform.
One method spammers use to impersonate other channels when leaving comments is to conceal subscriber counts.
A low subscriber count indicates that the person posing as another creator is not who they claim to be.
Many people on YouTube are concerned about comment spam and identity theft.
As a result, several updates are being rolled out to help protect viewers and creators from comment spam while also making it more difficult to impersonate creators.
