I have been receiving mysterious payments from ClowdCrowd

For the past few days, I have been receiving mysterious payments from ClowdCrowd direct to my paypal account. I know ClowdCrowd is connected with facebook, and if I remember correctly it is a paid to do task site. Funny thing is, I am not doing any task sites in ClowdCrowd for a long time already, so I am confused how I am getting the payments. For continuous 4 days now, I have received payments ranging from $0.05 to $0.15, small amounts but they come daily. The email address of the sender is Payments@ClowdCrowd.com from a certain "Servio, Inc." company. Anyone has some ideas where this is probably coming from? I would actually investigate more about this, but while I am investigating I want to know if some of you have the same experience, knows where this payments might be coming from, or knows something about servio, Inc. Its not that I am bothered about it, but I'm actually happy receiving payments from unknown source. But I just wanted to know exactly what I'm doing why I do receive such payments, or if there is some mistakes also know how and why?
