Second: Are you a lawyer? Is that the guaranteed outcome of such cases? Will it really carry no weight that they can (probably) substantiate their claim that you checked the box with a technically sound argument that their website actually works? A manual release test plan, unit tests, cucumber scripts?
That one, single checkbox, and the fact that you have to manually check it, is the legality upon which the entire business hinges. Especially if they're a little shady, they'd be sure to have their stuff in order around this.
I'm not a lawyer, but I am a programmer. I would never swear that my software works so correctly that I will use the actions of the application as proof that a user did check a box. If he claims he didn't, well, he just may be right. I've seen enough weird things happen not to trust any software to behave correctly all the time.
Now my technical reasons may not be relevant for a judge, but I doubt judges are very trustworthy of technology (they should have heard plenty of cases where technology failed and they will be users of all kinds of awful consumer technology, that sometimes, suddenly fails for no clear reason) and won't think favorably about a company with these kinds of practices. Perhaps I'm naive, but those things combined will lead a judge to believe you over the company.
