"Personally knows an employee of the company" is a strong signal that a person is not a bot, and may be more likely to be a decent person, because they are capable of maintaining enough of a relationship with an employee that the employee is willing to do something for them. The employee has already been vetted as trustworthy.

So that signal will apply to the first few people applying through this service.

Then some employees will get fired, the signal/noise ratio of internal requests changes, and employees can no longer get accounts reinstated via internal forms like this.

Basically this service will cause a brief spike in illegitimate accounts being reactivated, and then we will arrive at a new status quo that is strictly worse than the current one.
