What is the PTC site which frustrated you the most by not paying you?

Tweet

There are several ptc sites out there, and many of us register to more than one such site. I am sure that you must have met some site which failed to pay you or caused some type of problems. In my case i registered to Ohai Bux and Europe Bux a few weeks ago. I accumulted some money but not enough to cash out. One fine day Ohai sent a message that they will no longer be a ptc site and that they will not effect any payments, while Europebux showed that the domain was suspended temporarily or permanently. I was very frustrated. But nothing can be done. Can you share your negative similar experiences...
