Out of curiosity, I just tried again from same laptop that I got the come back in an hour message, and i am back in. Not that it is worth it, because it really isn't a good paying batch....re: Adsforce
Unlike any other requester I've worked with in 4 years on Mturk... this is the first time I've tracked Mac or IP address change, tipping an Mturk requester's batch, to halt my access to them. It took this pattern happening 6 or more times over a year or more for me to catch the pattern.
I've written them about it, no response. Your mileage may vary, and feel free to share what you find for a fix. My fix is waiting it out after an hour, and sticking to one computer only.
These MERLAMT look interesting...
