Yes, it is possible to get followers on social media without posting anything, but it's not very common. There could be several reasons why a page without any posts has a large following:
- The page may have previously posted content that has since been deleted or hidden, but the followers remain.
- The page may have gained its following through paid promotion or advertising.
- The page may have gained followers through partnerships with other accounts, cross-promotion, or collaborations.
- The page may have gained its following through a viral post that has since been deleted or hidden.
- The page may have a very specific niche or topic that appeals to a certain audience, and the followers are interested in that topic regardless of whether there is current content posted.
Lastly, they could have simply bought the followers.
