Thanks for the response guys. I think that upon receiving real mail, fraud seems unlikely. At least less likely than a random person registering from a random address in the IP zone. If I register from a hotel in Asia, does that sound like a serious business wanting to use your software?
Secondly... fraud?? a) demo license is free, so no financial loss if someone registers that isn't actually planning to buy a full license; b) money in the bank -> activate license, no money, disable license - seems like a pretty fraud-proof construction, so why care whether I am actually in the office or at home or even on vacation when I register?
Ok, so I should register from a fake address (the hotel is not my real address) to be allowed to have a real license? It seems this is the world up-side down. What happens when I return home and continue to use the producet, with a license, that is registered to a holiday resort in Asia?? Ohhh, of course, I have to go through the whole process again...
In my opinion, it's only a matter of accepting a real, potential client, putting one tick in a database field and everything is good to go. My information has definitely already been registered (upon retry I received the response that my email address was already in use), so it cannot be more than that.
So why do I spend my time writing here? Because I would be testing the software but now have some spare time on my hands. And I am a bit frustrated that something as daft as this can even still happen in this time in history.
