I would rephrase this post and ask: "Have you ever received any VALUABLE airdrop?", perhaps some people who got the Bitcoin cash distribution, if that qualifies as an airdrop at all, could answer yes. But may of the Ethereum "flavours and colors" airdrops were not worth a wei an unit.
Airdrops have been massively missused and now people just don´t believe in these.
Airdrop a good way to create communty and attract people to the project.
