Blox Promo at blox.promo or blox.land is another fake Roblox Robux free online generator. As with any scam, the deal is too good to be true, and, of course, isn't true. Blox Promo generates income by tricking online users into visiting and then showing them annoying popup advertisements. They also make income from surveys, which they trick visitors into completing. But, it doesn't matter how many surveys the visitors complete, they will never get the Robux they were promised.
