I am offering Instagram ban services. This means I can ban
any account as long as:
- It's not verified (there are some rare exceptions so ask me anyway)
- It has a name
- It has a face in the profile picture
How do you feel if someone bans your Instagram account? Don't you feel any guilt about offering this service? Always know that if you do something bad for others, it will come back to you.
There is nothing permanent. The account can always be unbanned again if it was banned for no good reason.
So people are wasting their money to ban the accounts as it will be unbanned.

The account can only be unbanned if the owner can prove real ownership with his true name which is rarely the case. Anyway, anyone paying for the service knows the exact pros and cons of it don't worry about that.
