I am still using neobux for the Crowdflower tasks but most of them are not that good anymore,many unfair corrections,low payments and jobs that not worth your time.
Fortunately, the rainforest tests are an exception their payments are very good and they are very easy to do,usually i earn about 150$ every month from rainforest tests only which is ok for me since i don't spend much time for them.The bad news is that the registrations have closed recently and they don't accept new members anymore.
