I have been using Gener8 for about a year now. As they are in Beta still, the rewards the platform offers are limited, but gradually increasing, for example previously certain items were capped in amount one person could redeem, but are now unlimited. I myself have currently redeemed £55 worth of Amazon UK vouchers with them, most recently this morning, which I quickly put towards my pre-order of the new Transatlantic album. Other rewards are available, but Amazon £5 vouchers are the easiest to get since as the most popular item, they release more of them in the drops.  

This is currently a UK only thing, though people from other countries can sign up and start earning tokens in advance for eventual expansion to other territories. This is not the sort of thing I would normally post to MMA, but I thought what the hell, this is a good thing with a lot of potential here and despite initial appearances, it's absolutely not a scam. The community here have my word on that as an MMA admin. It sure as hell beats Ad Block, which has become less and less of use in recent years.

This is a link here that you can sign up with, if the idea of free money appeals to you and you'll be using your computer anyway right?

A word of warning: don't expect easy free money if you try it out. You will need two referrals of their own in order to access every marketplace item. Stocks are also limited while in Beta, and believe me, they really do sell out quickly. But the more people who give Gener8 a go, the closer they will come to getting out of Beta. That means more rewards for everyone. The guys behind the project currently fund most of the rewards marketplace stock out of their own pockets. As more advertising firms partner with them, the more stock there will be. 

The idea behind it is interesting though. I should really see about getting onto their CS to see if they can fix my account.
