This reminds me of a time when Facebook paid people to keep an APP on their phone without doing anything with the app in return, they will pay you $30 every month at the end of the month, which may be more than the amount as it depends on your location, I believe New York (US) were highly paid during that period to keep the app running in the background and some people were using VPN to bypass the restriction from forbid countries and after few months, they ended the loyalty program.
There are two sides to the outcome of a paid tester, the company may receive inaccurate data from people because most restricted users would want to use that opportunity to earn as well, and anyone who agrees to receive a penny for their privacy to be used as a lab rat does not value himself/herself, you are being paid because they need something from you, otherwise, they would have used their family members. We should value privacy above money.
