Honestly you should be concerned of yourself getting drained due to randomly following airdrop, in fact, right now TON is among the hottest blockchain that it causes so many scammers and phishers to infest into the blockchain and creeping up into its whole ecosystem.
if you don't want to lose your asset, just never interact with airdrop at all honestly, you better off not doing anything airdrop related if you really don't have any idea, the scamming scheme varies so much sometime newbie having hard time recognizing one.
but if you insist, just follow airdrop that's coming from reputable project backed by reputable investor, at least you know who's behind the project in case things go south.
it kind of reminds me LotteFi scam, this whole project is created by scammer that tries to steal money for you and it happened in TON as well, these scammers just never stop.
