No it’s not a scam, although lately it seems their partners may be scamming members. I have been an inboxdollars member since I believe 04. Last year they introduced the tv channel, just another way to earn first it was earn up to $2.00 a day viewing this channel then they capped it at .50 which is fine. It takes awhile, you see the same videos over and over again. The player eats up memory, retaining more than half of my 12gigs sometimes.
The only reason Springboard didn’t rank higher on our list is because some users have reported a fairly limited supply of available surveys, making it difficult to reach the $50 minimum cashout threshold. However, the availability of surveys depends on your demographics — so my recommendation is to join, making sure your profile is 100% complete, and then see if enough opportunities come your way to make it worth your while.
The only problem is with this site now to do surveys you have to put your cell phone number in before they will let you (Only once) they shouldn't ask for this for one for two they won't take my number so i'm blocked from doing surveys. I have to say one way it's bad the other way it's worse and all i can say good about this site right now is they do pay.
I don’t see PaidViewpoint on your list. I like using that site. I signed up for it on June 28, 2016, but I guess I forgot about the site and stopped using it on July 24, 2016 but had a total of $1.91. I started using it again on May 5, 2018, and I’m now up to $27.05 and have a trait score of 10, which is the highest. The surveys are easy and you don’t get disqualified. I mostly earn 10 cents, but once in awhile I earn some good money like 62 cents. It does take awhile to add up, but it’s free money.
How it works: YouGov is one of the world’s largest research companies, with over 5 million members worldwide. The company provides market research and polling for major corporations, as well as political campaigns — particularly in the United Kingdom, where their polls are frequently cited in the media. Most surveys take between 5 to 10 minutes, and earn you 1,000 points. For reference, 1,400 points is worth about $1.
