If this is remotely true, it is absolutely the exception to the rule. Yes, they take all of your info, then you spend endless amounts of time filling out the prequal for a survey only to get disqualified. If you do happen to be qualified, well the 15-30+minutes you spend to “make” that 25-50 CENTS is NOT worth the time. Again the user claiming to make anywhere decent amounts of money from this is the exception rather than the rule. Don’t waste your time.
I have been using InBox Dollars for months. I earned my first $30 and cashed out. I referred my Wife and she signed up and started doing surveys. Once I reached $75 and she reached her first $30 we cashed out. The next day both of our accounts was suspended. How convenient. We spoke with a Live chat agent to explain that the accounts are separate but they didn't care. They just hurried us off and ended the chat. Months of work all gone. INBOX DOLLARS IS A SCAM!!!!!!!!! Do not waste your time. They will use you for your services then find some reason to not pay you.
In addition to the free offers, there are “paid” offers, too. i.e. Buy a bouquet of flowers through an online florist, get $7.00 back in your InboxDollars account. Lots of similar cash back offers for subscription box services and eCommerce sites. If it’s something you were already interested in, it’s not bad. Otherwise, no point in spending (read: losing) money in order to make money.
