Although Simplesat's able to filter out most spam feedback, some might slip through the cracks resulting in feedback from an "Anonymous" customer. You might also see positive/neutral/negative ratings all with the same timestamp. 

This happens from bots clicking links in emails from your customers (checking for spam or viruses).

If you continue to see this in your account, please let the Simplesat team know so we can investigate for you in more detail.
