Hello everyone, recently I saw a travel agency that has been promoting their giveaway. As long as you follow their newsletter, you can participate in the lucky draw. The prize is a free half-month trip to Southeast Asia.
Has anyone participated in this type of sweepstakes? Are there any security issues? By the way, the lucky draw page is here: https://www.odynovotours.com/newsletter/
This company is called Odynovo. Through their review page, I see a lot of visitors using their service, so I think they should be trustworthy. But I still have no idea about this giveaway.
