There are many fake bots that are linked to real bots for several reasons:

1. **Increasing engagement**: Some advertisers or content owners use fake bots to increase the number of followers or interactions, giving the impression that the content is more popular.

2. **Improving social appearance**: Fake bots can help improve the social appearance of brands or public figures, which may lead to attracting more real followers.

3. **Manipulating results**: Some parties use fake bots to manipulate search results or ratings, which can negatively affect competitors.

4. **Testing systems**: Sometimes, fake bots are used to test systems and applications, and ensure that they are able to handle a large number of users.

5. **Promoting products**: Fake bots may be used to indirectly promote products or services, which increases the brand’s visibility.

These uses can be risky, as they can lead to loss of credibility or even penalties from social media platforms.
