A while ago I read a case about "Psynina" which was booked in the past, including advances of money by part of the organizer, however this project never showed up on the place and date probably for very obvious reasons.
However, you are right that the post does not focus the attention to "Psynina", but to a current and more serious situation, which was discovered by many artists in the present, where there's even exist a private group of victims of such scam and such violations of author rights, that sum more than 100 artists who are completely aware of it, and this, without forgetting the hundreds of artists who are not even aware that their works have been damaged during more than 10 YEARS by this man and in several ways. You'd be surprised how many of those who are aware now, realized the situation many years later. This doesn't take long to explode and It's a pretty grim and bad situation for the responsible, unfortunately for him, but it is a situation that more than sure that will be pursued. In Beatport, for example, many of their record labels under Plusquam have already been banned and you won't find them anymore.
