We're going in circles, so this will be my last comment on the matter. In our experience, over an extended period of time, there was virtually no legitimate use originating from Mailinator users. Maybe it's a fantastic service for others. For us, it was hands down the biggest source of abuse. It would be extremely difficult for anyone to convince me of its legitimacy in the face of the data we saw over a prolonged period. And it's not even that Mailinator users would sign up, try it for 30 minutes, and then just move on. In that case, I'd just say they weren't qualified, didn't like the service, didn't find the value prop, whatever. But that's not what happened. I don't really think the "you're going to get screwed, so just learn how to get screwed" attitude is really appropriate. There have been a few armchair theories on how we should have dealt with the issue. Suffice to say, 10 paragraphs of text here aren't going to enumerate everything we tried. And it's not as if we made no product improvements in that period either. Simply put: if you don't want to use the service, great. If you don't find it valuable, that's fine too. But no one's taking the high road trying to perennially use a service without paying for it, meanwhile calling it a quality issue. And none of this is abstract. We tried all sorts of technical solutions. People just found another way to abuse. We slapped the credit card gate up and had not a single Mailinator signup for the 2 years after that. It simply solved the problem. Maybe someone will up the ante with fake credit cards . . . for us, we found thousands of Mailinator users weren't willing to take that step.
