OK, After analysis of this site, I have arrived to the conclusion of how this site profits.
First go to: http://www.giveawayoftheday.com/for-developers/
And see: "First and foremost, you have an absolute guarantee that you will be paid for your software, even when the software is distributed within a special Giveaway of the day offer. Our company will pay you for your software, thus protecting you from software piracy."
As you read this, you naturally find yourself realizing that Giveaway of the Day MUST LOSE MONEY BY PAYING THE DEVELOPERS.
So how would GOTD earn profits to stop themselves from going bankrupt? After analysing this site, The only way for them to do this is to have advertisements. People who are part of the GOTD team (such as Lee, a moderator) have testified that advertisements are an integral part of this site and say that the reason I can't view them is because of my firewall. Well, lets have a look at this, shall we???
A. Firewalls, DO NOT block advertisements. Everyone knows this (including a proficient computer user called "bolon"). Firewalls only prevent hackers from accessing your PC via the internet.
B. Turn off all your firewalls, antiviruses, ad blockers, etc. and there will be no ads in this website! That's right NO ADS
So, I cannot find a way to see how GOTD profits from this. Nobody, would want to go bankrupt. So, why is GOTD doing this, What's the catch?
Guess what, it is probably SPYWARE! Yes SPYWARE! Trojans, viruses, worms etc.
Recently, some "giveaways" have been detected by my security software to contain possible spyware and viruses. In addition, some programs reportedly had trojan horses.
Lastly, upon installation of some programs, a blue screen of death mysteriously occurs along with a system crash.
I don't know whether this is intentional or not, but I'm not going to stick around here to find out!
