Set Account Master, oscar smith, Real Estate Research are super fast requesters. Imsportz admin has dead i think after uploading the hits. Really very very slow pay by imsportz admin.
Inveni movie suggestion HITs. It'll get approved the very next second I submit the HIT. Never seen anything like it.
I have been doing some Crowd surf today and all of the transcriptions were approved within minutes of my submitting.
Ignite Media Solutions has been the slowest, in my experience. Some Crowdsource (especially the writing HITs), too. Matt Rubin used to be fast, but most of my pending stuff is from him right now. All of them have been 7 days plus waiting. NetMSI, you'll be waiting FOREVER. I've actually had the full 30 days go by on auto-approve with NetMSI before. Ugh. Medcrowd is easily the quickest of the bunch - usually approves within minutes, another reason why I <3 them so much. The few times I do Oscars, they're always also approved quickly. Coman Petre, when he had his parenting question HITs up, was also fast.
