Teambuy and Dealfind are definitely going into bankruptcy by the looks of things and the people who will suffer are the merchants who are not going to get paid and the customers who signed up to receive Teambuy offers and now their contact info will be sold to the highest bidder. So, expect to be spammed a lot and your email to be filled with junk offers.
Here's something I found straight from Teambuy's privacy policy:
We may transfer personally identifiable information as an asset in connection with a proposed or actual merger or sale (including any transfers made as part of an insolvency or bankruptcy proceeding) involving all or part of our business or as part of a corporate reorganisation, stock sale or other change in control.
