I want to know the word for person or group of people that I follow.
I tried searching on the internet and found nothing.
Depending on the context the person or group can have different names:
Leader - The person who leads or commands a group, organization, or country; One who guides others in action or opinion; one who takes the lead in any business, enterprise, or movement; one who is ‘followed’.
Guide - A person who shows the way to others, especially one employed to show tourists around places of interest.
This person can also be a commanding officer (CO) in the context of missions, a conductor, maybe a profile or an account.
There is no general term for this in English other than leader, but social media has given a new meaning to the term follow, meaning to subscribe to status updates, and you can't call the person you're following a leader in this case.
Depending on your context you may be able to use the terms publish/subscribe or even publish/follow but that is unlikely to be understood by many social media users. However, a term that might work across multiple such services is account, since it can be said you follow both a Facebook and Twitter account, for example.
