Airdrops can only be scams if they require you to pay in any form
Really? Dude, all tokens created by scammers for PUMP AND DUMP schemes are using "FREE AIRDROPS"
Let me explain you shortly how it works: 1. Scammers create millions of free tokens via Ethereum platform. 2. Announcing some shitty project with attractive name here on bitcointalk. 3. Airdropping 10-20% of tokens to applicants. 3. Listing token on free scammy exchange like Etherdelta and IDEX. 4. Pumping the price via fake buy orders that are allowed on decentralized exchanges. 5. Dumping their bags (80% of total tokens) and vanishing with money. 6. In some cases greedy scammers are announcing fake swaps to get back airdrop tokens and to sell them too (That's what you are doing) The good example of such classic scam is Ethereum Dark https://bitcointalk.org/index.php?topic=2297270.msg23309128#msg23309128https://bitcointalk.org/index.php?topic=2297270.msg25237081#msg25237081
