I'm sure a lot of you on here will be well aware of 20cogs, it's similar to ohmydosh in that you complete offers (such as trying free trails, downloading apps, etc.) for money. None are too spammy and even if you match betted previously (so are unable to do the gambling offers, they offer 1 per cog) you can still easily complete the 20 offers in a few days. You have to wait 30 unfortunately to cash out (some of the offers take a long time to validate).
Most of the offers pay you between £5-10 a pop.
In addition, they have a very generous referral scheme which you get 5% of someone's earnings for a lifetime as well as £10 when they cash out.
Website which offers £5 bonus for signing up through the above link. Pays you part of their referral commission for free trails etc. There are 20 “cogs” (things to sign up for or compete) each cog has multiple different offers and you can complete more than one for each cog. when all 20 cogs are complete you can cash out to PayPal. I earned £194 but could have been more if I hadn’t already signed up to a few of them.
