I believe about 90% of the airdrop is fake. They don't want to give tokens. They do not employ different tactics to trap people. But they do not want to pay any coins. At the end of time can no longer find them.
Agree, there is too much airdrop scam currently because creating it is so easy. We need to be careful when participating in these airdrops because most of them will make us lose time and not receive anything from them.
