Yes you correctly have made that have focused attention on this topic.Indeed a lot of scams under the guise of airdrop collect information about You.That's why I don't participate in all airdrop.If the company is good and it conducts transparent airdrop, then you can easily participate.
If you kmow airdrop attemp so high scam and why there re many people still join in that bad attemp airdrop project?
I think we should stay away from this kind of airdrop. Avoid get scam by not joining the airdrop is the best step we must do.
