I'm trying to earn some extra cash this summer by working online. However, I've noticed that a lot of websites which I've signed up for (e.g. Swagbucks, Neobux) rely heavily on you referring people in order to get a decent amount of cash. I don't like sending out referrals, as hardly anyone I send them to signs up as they just assume it's spam. I'm currently using Postloop and Slicethepie, both of which have been ideal as they just involve me writing small amounts in order to get paid. That's the kind of thing I'm interested in. Has anyone got any suggestions of sites which operate in a similar way? No sites which I need to pay for/invest in, please, as I can't afford this - I only have around $200 in my bank account and this is to cover my living costs for two months.
