Personally the thought of un-orthadox call backs and the spying method as whole makes me not want to buy add-on's from certain developers in this thread. I pay money for my server, nor do i know you, so in aspect why should i allow you to monitor my server after giving you money?
Piracy is something like the war on drugs, gl trying but your better of dying before you accomplish something. Not trying to be harsh but i am a small developer/artist myself and piracy affects me to, but what bothers me is the "lack of privacy" some of you are speaking of.
It's a 2 way street, without it many popular software wouldn't have as many paid clients as it does now. Not implying it's a good thing to pirate anything, just simply stating with every - there is a +.
Want more sales and less pirating?
- Advertise more.
- Respect the clients privacy.
There are ways to combat it, but disregarding someone's privacy is quite arrogant and not the route i would go as a developer.
Just my 2 cents.
