I don't really see a link between Crypto Youtubers being shills and there not talking about Alphabay. Many people don't even use Tor and may even shy away from using Alphabay because many of the products traded on their platform and therefore have no care about what happens to it. Secondly, what if you are a Youtuber that uses Alphabay to acquire goods that are frowned upon by your country. Do you really want to put yourself on the radar to be looked at?
Now, I will admit the Kraken problem is weird.
But Polo? Polo went down as a very suspect platform for me months ago. DDOS attacks or problems with their platform on a consistent basis when coins were going up or dropping like a fly happened one too many times for me. And the SBD/Steem Transfer problem makes them even more suspect too.
