Ha! You being a newbie to BHW, I can see why you may think that but anyone who has been here for a while knows better.
Anyone thats been here a while should know how easy it is to fake accounts, thats a core of most black hat tachniques.
Listen, it's good that you want to support a sellers project but you need to respect what other people are saying otherwise you'll just end up getting scammed and encouraging other people to let themselves get scammed.
In the email that was posted on here that I saw, it didn't say you were prefunding the plugin, it said it was almost finished and about to be released.
If there was delays due to the development anybody with any sort of experience would have allowed for contingencies, either Shezboy isn't telling the truth or both him and you are being extermely naive and even more so for someone who apparently has as much experience in this as he does.
Last year when the jacker stopped working for the first time, people were telling him months before that Facebook was putting in blocks and it was no longer working for them and that it would stop working for everybody else. He, denied it over and over again, tried to blame it on the person, saying they hadn't set up correctly, told people they had to warm up their accounts/domains, then when he did agree that there was going to be a problem told everybody that his team already had a way around Facebooks update, encouraged people to keep buying that he would have an update, which he didn't.
Also, this is at least the 3rd time this has come up. Shezboy started sending out emails that he had a new Jacker within months of closing his BST, and the set up was the same, buy at prerelease cost a few weeks before or pay double once released, then he would say there was delays. There has been multiple posts here where people have said they have asked for proof/evidence that he has a working jacker etc just for him to block them or stop responding.
I could write a lot more about how his emails/BSTs and other posts I've seen of his contradict each other and don't add up but I don't need to give any more time to this.
When people first started saying the jacker wasnt working over a year ago I was the same as you, I was on shezboys side and probably a lot of people were. When his buyers said they had a problem I would agree that they probably haven't set it up correctly. When people said Facebook was updating, I agreed that Shezboy just needed time to fix it. When it got to the point when he couldn't fix it anymore, instead of owning up and refunding the people who hadn't been able to use his product because Facebook was already blocking at the same time he was still selling, instead of manning up and giving a clear acknowledgment that his product no longer worked, he ran away and made up excuses not to reply to his customers.... It should be clear what type of person shezboy is.
