I made this mistake when airdrops in the past were quite a lot of attention. Even though I didn't use my main wallet, I still kept some in a wallet that I unknowingly connected to the airdrop web to claim tokens. I used to always create a new wallet, but my mistake was not doing it at that time. I was still lucky enough because the amount was not large.
Also, be careful with some advertisements in telegram groups and channels, they promote certain sites. as well as unknown accounts or those who pretend to be other people to make certain offers. when we are more active in the online world, then we must have knowledge regarding the possibility of bad things happening.
