Is Stickr a Scam or a Legitimate Car Decal Advertisement Company?

There are some Facebook advertisements that claim members of stickr.co can make up to $500 per month, but some persons have complained about making less than the amount they pay for membership each month ($9.99) and the one-time membership fee of $19.99.

Here are some of the complaints:

• "Hey everyone, I just got a full month's pay. $3.01..."
• "...I just got paid 1.90, they didn’t reimburse me the monthly membership fee..."
• "I did a full month membership as well and just got the payment. A whopping $2.10! ..."

Also, it seems a lot of people are not aware of the reoccurring monthly charge of $9.99, like this person who left this comment:

"...I paid the " one-time fee" (yeah right!) I got the Stickrr, put it on my back window, took a picture and sent it in, then about 3 weeks later I get an additional charge on my debit card for another $9.99. But you see, I paid the premium amount upfront which was $9.99 plus $29.00.

They said if I paid this amount I would get all my stickers sent to me free of charge, so I thought it was worth it, but when I saw the additional $9.99 on my bank statement, I sent them an email to request that they return my money because they must have made a mistake.

I explained in my email that I was a premium member and should not be charged any further fees. They wrote back and told me that the $9.99 was for the monthly membership fee. I never read anything about a monthly membership fee when I signed up. I sent a reply telling asking them why would I or anyone pay you $9.99 to advertise for you? They never responded..."
