I kicked him because he implied that it was impossible to cancel payment. I doubt he really intended to leave the site, I think he just wanted to make a drama. He was quite meticulous and I'm sure he would have found how to cancel if he really wanted to. Or at least he could have asked me, because he kept sending his reports to my private chat. I probably blocked him from the panel at that time for something he did there, but this part I don't remember already. Anyway, he had chosen to make a spectacle instead of writing to me privately about the matter, which he had no problem doing about other matters at that moment.
Porn industry was known long ago for it's shady billing practices. In the beginning of 00es there was a lot of porn sites that asked for credit card number to verify age and promising not to charge it, but having a small print that they will charge it after several days if the member does not cancel and was doing so, charging sometimes even several dollars every next day, so it could add up to $70-$80 before user would notice it in their bank statement (which at a time users could not see online, only got it in paper mail next month). There were sites that promised a lot, but had just a couple of videos inside. Some sites had cancel link hidden or absent. And some other scams. I never used any of those shady practices, was always abundantly clear about what user gets if he pays, never hidden cancel links, etc. Also, by 2016 I could not do most of the scams even if I wanted, because payments for porn sites were already heavily regulated. In fact it's about 10 times easier now to run some kind of billing scam under non-adult billing than under billing that processes adult sites. Still it was more important that I never wanted to do anything shady and always tried to be as direct as possible about billing and cancellation process. So naturally I was very annoyed by Johns implications and kicked him out.
