Totally agree with you man; I paid for the course, got access to the group, received messages up to the point where I put out some really mild criticism because he advised on coins after 30-40% rise had already been. Actually, not even criticized but made suggestion to send out messages sooner. From that day on I did not receive any more messages and was blocked.
Luckily there are a lot of interesting people and groups out there because I won't certainly call it analyzing what Suppo does.
