Apparently it is true that Perk TV flag each account for defects, the more defects you have the chances of your rewards get cancelled or account banned. Defects such as watching the same video on multiple videos, you know you can’t be watching all five devices at the same time can you? isn’t call cheating or taking advantage to get more points?
Every so often or once in a while, Perk TV will also do an audit system check such as checking your address location versus your IP location, and if the location of your devices address don’t match then your reward cancelled and eventually banned if you cannot provide Government issued ID.
Perk does a lot of flagging and auditing. If any defects for sure your account will be in trouble.
