I have left working on PTC, Microjob, as well as GPT sites. I am on a couple of PTP sites but I am staff there, so I am not just there to earn from paid posting. I am no longer working on low paying sites. Micro job and GPT sites offer easy jobs like app installations, website sign-ups, etc. and these tasks don't demand expertise. Paid-to-post sites allow individuals proficient in English to earn from short and long posts on community and article sites. However, a decent income is a far cry.
