It's not a good idea as people would later found out. It's hard to keep up a fake community, even if you have people to help you. All communities I was part of were usually gaming communities so it's easier to get members if you have a wide variety of games. I don't feel the need to, though. I think I'd do it if it's something else, like Instagram Followers/Comments/Likes, Facebook Likes/Comments, YouTube Views/Likes/Comments/Subscribers etc, but not active members in a community.
