...On the Google form is something else, they were asking for our trust wallet Recovery phrase.
This is exactly a scam.
A scam will always ask you several things that are very annoying and also important details, such as:
1. Asking for the important and crucial details like private key, PIN, Password, recovery phrase, and others.
2. Asking you to deposit funds in order to withdraw.
After you deposit it, they will be gone.
3. Promising for high profits
It is like when they do a scam investment, they promise us big profits that will really attract many people, especially the newbies.
4. Giving big rewards
It also happens on the scam that they run ta program and the participants will get very high rewards by doing easy tasks.
If you meet at least those 4, it is better to leave it, because it is commonly and mostly a scam.
Nice points, I think you can make a topic on how to identify fake airdrops with these few points you listed, I bet it will be really helpful to newbies, so they can be able to identify fake airdrops when they see one and stay away from them.
Infact there are many scammers around and when we talk about airdrops there are many fake ones who are infact try to steal your data to hack your wallet or use your data to claim rewards from other campaigns.
So do not be greedy and be watchful all the time online.
Airdrops are now a shadow of itself, unlike back then, scammers tend to take advantage of anything in other exploit and loot money from people, we just have to be careful.
This type of scam has been around since the early days of crypto wallets, I I also doubt exchanges that required users' private keys.
Participating in the Bounty or Airdrop is your own decision, but never hand over your wallet's private key/seed phase/password to others. It's the fastest way to lose all of your wallet's assets 
Haha, I'll never do such,thanks alot for the advice, will just stay away from any airdrop that looks suspicious.
