There have been alot of scam project now...
Three features of fake airdrop.
1: any airdrop that "have no end" they often runs for 2/3 months, majority are not true. real airdrops don't last more than a month.
2: 95% of airdrop given to "all participants" is not real. Normal airdrop is mainly for a limited number for top referrals.
3: Any airdrop promising you high amount of their token equivalent $5000, $10,000 or even more without through referral bonus may not be real. Real airdrops don't give such amount, unless you are claiming on their site where you pay gas fee,
Also, the group of the Airdrop project on Telegram, if it contains spam, bots, and admins do not answer people’s questions, then know that it is undoubtedly a fake airdrop. Most of the new Twitter accounts that do not have many followers and that promote airdrops and NFT giveaways are accounts that were created in order to deceive people and increase followers. Also, the airdrop website, if its script is primitive and unprofessional, or the whitepaper has plagiarism, then the airdrop coins will be shitcoins in the future.
