Airdrop scam tokens on the BNB Chain are fake tokens that aim to lure users to scam websites by showing a massive USD exchange rate, but in reality, these fake tokens have no value and cannot be exchanged or transacted upon.
Instead, when a user has a fake token and finds they cannot exchange it, they are either directed, or their curiosity leads them to a faulty / scam website corresponding with the scam token. Once a user is on the fake website, they are asked to connect their wallet and, in return, gain approval to exchange or transact the token.
