They ain't give away no Lamborghinis, LOL. You ever hear of anyone here or anywhere got a Lamborghini or $200,000 of BTC? It's supposedly happened 10 times! 5 other sites using FBC's design also claim to be giving Lambos.
So, you're accusing them that Lambo lottery is fraud? You need to have some proofs for it because now it looks that you're just angry at Freebitco.in. BTW, guy few posts below you showed posts of 2 winners, so, you can't say that nobody didn't saw winners.
And these sites with same design have no relation with Freebitco.in, it's just copycats and it's likely that they're not legit.
