Everyone has his own celebrity. Lot's of people follow lives of different actors. Some of them watch the lives of sportsmen. For me such actor as Ryan Reynolds is a perfect person to follow on social nets and in the real world.
He's a world famous performer in many different films and TV series among many types of them. For example, he got a lot of attention thanks to his roles as a mane heroes in films "Deadpool" and "Free guy".
Ryan is very confident about his connection with fans. He's so glad to have such big amount of people who follow him. Reynolds attends many different TV shows and meetings with his fans to get in touch with them.
As I know Ryan doesn't sell or advertise anything for money. The only thing he can advertise is a company which payed to thr director of the film he takes part in. So ut appears so that it's not a personal advertisement from him, but advertisement in a film.
Of course my celeb uses social media to collect fans around him. This way he can tell the public about something that happens in his life or announce something to his fans that they might be interested in.
But I'm not really in his official fan club. I'm just a connoisseur of great films. And many movies Ryan took part in are very great.
