While they may work, do realize that in the long run you're being scammed from that. The people that run those kinds of sites get so much money just from website traffic. They get at minimum 2x profit than you do by doing these "offers".

As for the Robux giveaways stuff on platforms like Discord, those are scummy. It promotes spamming and are ran by fishy people. Please, obtain your Robux by actually purchasing it from Roblox themselves. There is no reason to go to third party sites for it.
