Hijack users may not have bad intentions; they simply want to use your product for their own purposes, which can ultimately hurt your business. If a user generates enough revenue to justify the customer support time, they can be considered valuable; otherwise, they may not be worth the effort, especially if they don't contribute to learning or product improvement.

Hijack users, like those who misuse platforms for illegal activities, can be detrimental to a business despite potentially generating revenue; their negative impact often outweighs any positives they bring.

There are users who create no long-term value and may even harm your network; these hijack users should be identified and removed from your platform.

When startups begin, they often try to attract every user possible, but this can lead to unwanted users who hijack the product for unintended purposes.

Startups often struggle to identify and remove hijack users, focusing instead on users who provide some value, which can be detrimental to their growth.

Identify bad customers who exploit your product without providing value; these customers can mislead you and waste your resources.

It's important to recognize the spectrum of users: some use your product as intended, while others use it in interesting ways that could lead to potential business opportunities.

Some hijack users can actually lead to valuable insights; for instance, video gamers on Justin.tv prompted the idea for Twitch, which became a significant community.

While it's okay to explore unconventional use cases, businesses should not allow disruptive users to influence core product decisions or features.
