Pokemon Go Niantic to Revert Strikes for Players who Incorrectly Received Punishments

Trainers, Niantic and Pokemon Go will be reverting strikes for some players who incorrectly received punishments.
Niantic Support announced on their Twitter account that they are working on reverting strikes for some Trainers who incorrectly received punishments on their account and this process will be done automatically.
We’re glad that they acknowledged this mistake and are reverting the incorrect strikes. To be honest, they should give compensation to these players.
We’re working on reverting strikes for some Trainers who incorrectly received punishments on their accounts. This will be done for Trainers automatically, whether or not they have contacted us. We apologize for the error.

Have you gotten a strike without any justifiable reason?
As a strike is not visible thing for a trainer how do we know if Niantic is actually doing anything?
