LinkedIn has been known to have a pretty low ban ratio. In other words, the company is not too quick to suspend or delete accounts.
This may be due, in part, to the company's focus on providing a platform for business professionals to network with one another. As a result, LinkedIn has been careful not to disturb the user experience by suspending or deleting too many accounts.
That said, LinkedIn does reserve the right to suspend or delete accounts that violate its terms of service agreement. So users should be sure to read and understand those terms before creating an account.
In my experience if 100 accounts manage will get ban 10 to 20 accounts is normal .
