What exactly do you mean by "websites like this"? FreeBitco.in has been around for a decade and is still going strong. Anybody who is familiar with the site can attest to the legitimacy of their bonuses. If you have any evidence of a possible exit scam it is your moral obligation to share it with the community otherwise you are spreading FUD with baseless accusations. It's strange that so many newbie accounts have recently commented in this thread to accuse them of dumping on Uniswap, having no funds in their withdrawal wallet, and now fake bonuses and exit scamming. Their claims are either easily debunked or just never substantiated with any proof.
