One question that came up from friends is why some of these sites and particularly the better ones often require an ID verification to withdraw. It didn't bother me, because I see why they do that. Because there are so many scams out there, I can see why one friend wondered "Why are they collecting my information?" and "are they selling my info?".
The answer is that like you, the companies that put sites like this together work hard on what they are doing. They don't want to fall prey to scammers either To one degree or another they want to keep things secure so that they are also doing ethical huisness with their clients on the other end, and stay within legal boundaries.
One reason is that some countries and states have laws probibiting minors from joining sites like this. The reasons for those laws vary, for instance some of the games have casino gambling, or offer optional in game purchases. By verifying your ID they are covering their backsides for when some kid decides to try to use Mommy's credit card to buy stuff in a game without permission. The games themselves are owned by the developers, not the GPT sites - but there still could be legal questions if they were providing an inappropriate gateway to minors.
Another reason some GPT sites require verification is to make sure people aren't creating multiple accounts to be able to repeat the same offers and surveys.
Their clients who want to promote a game are paying to help get their game seen and played by more people, while developing and improving thier game from more feedback. The makers of those games are offering you a reward for trying it out, not for trying it out 12 different times!🍿🤣
If you are using these sites I don't recommend trying to play the system like that. Chances are you won't get paid, and might get yourself banned, just sayin'.
Equally, people paying to get information from a wide group of people don't want the same person doing the same survey. That would be boring anyway, but it would really screw their results up. Verification of ID confirms that the user is of age and not a robot, and therefore a possible source of valued information, and makes it easier to ensure each participant is unique
So, YES, I'm relatively ok sharing my I'd for payment verification once when I join a GPT site. If you feel concerned, look for the faq on each site, they usually explain why they require this, and state their policy about how the info is used.
On the other hand, realize when doing the surveys that you may run into things you don't want to share. What they ask and what you chose to share is not created by the GPT and paid survey sites, but their clients down the line whose motivations may vary. Typically I avoid sharing my phone number and address when it comes to that, to avoid spam phone calls and junk mail. Sometimes I do, for instance I gave my contact info to a Harvard University reaserch group offering a higher paying lengthy study. Just use good judgement and you'll be fine.
