Any ICO project managers, community managers, or e-mail folks have any experience buying lists from websites like
https://cryptoemaillists.com/? They say they purchased from closed ICOs so they're confirmed buyers. Seems to me it's a clear path to ROI but have no idea how to think about this.
This topic is quite contradictive in my opinion, because in one hand, people are giving their confirm to them to give an e-mails to third persons, but it is not 100% fair as well.
