There are a lot of garbage in this area, and even those tokens that are sent most often do not even make sense to sell. Choosing Airdrop is just as hard as it is good ICO.
Airdrop is a warehouse for fraud, so I started to avoid it. at this time we cannot rely on Airdrop, so I prefer to move to Bounty which I think is more reliable. Airdrop is a free coin so it's no wonder the results aren't satisfying.
