I disagree with you. Aggressive marketing is just a type of marketing that works very well in a short timeframe and gives a huge boost to brand's awareness. Logically, every new service should come up with aggressive marketing at first, otherwise they won't become famous anytime soon. Since you mentioned Chipmixer, I spend an hour to learn them a little and as I see, they absolutely started on this forum with an aggressive marketing. They also came up when one of the most famous mixer left the market. So, Chipmixer took an advantage of the moment of Bitmixer leaving the market, then they came here with a review campaign and started a signature campaign with pretty good pay rates, hired a lot of participants, kept the fixed bitcoin payrate when it was going up and up. They were paying hundreds of thousands of dollars per week. Chipmixer was no joke, I can't compare Whirlwind to them. Don't know much about other signature campaigns but I bet there must be many companies that did aggressive marketing and still operate on this forum. Probably Stake? Idk.

I think the situation for whirlwind was the following: They had two plans, either stay on the business or if it wasn't going to become profitable, then just exit. I believe their intention was not to scam when they decided to start this business but as it seems, their plan didn't work, the money that they were putting into campaign didn't bring back enough profit. But I don't know why did they left $40k in escrow with minerjones.
