There are a whole bunch of apps that pretend they have the power to unlock private Twitter accounts for you. They are all FAKE - there is no exception to that.
Luckily, there is a genuine way to view private Twitter profiles, but it will require a little bit of work.
Essentially, you will need to create an account that is genuinely interesting enough that the user will want to follow you.
If you already know the person (maybe from school or work) then use the information you have about them from real life... Their hobbies, passions, or interests.
If you don't have anything to go on, you will need to do some online research.
Interestingly, many private profiles on Twitter still ill out their bios, which is a great way to learn what kind of profiles they are likely to accept follow requests from.
For example, the profile above is likely to accept a request from someone who is also a Justin Bieber or Arianna Grande fan, so it's all about getting some tweets out there that reflect this.
Here are some other considerations:
- Don't create all your tweets in one day, you might look like a fake account. Give it time.
- Add something in your bio which explains why you would be sending a request (for example, "looking to meet other Bieber fans")
- Use images in your tweets where possible. It'll make your timeline more exciting.
