[Toby Benson]

You always have to check if they have a legit website and check their whitepaper and roadmap

actually, its very difficult question to answer. majority of airdrops are scams.but there are some with good projects. for differentiate this, you will have to study about each and every project. its time-consuming. however for getting maximum benefits from air drop you have to upload google sheet as soon as possible.so i advise you to just fill each and every airdrop form and submit them as soon as possible and just forget it. if they asking for a donation,if they asked to register on a site, if they dont have twitter/facebook account or bitcointalk ANN tread..keep on mind majority of them are scams. so never donate for getting airdrop
good luck

Most airdrops do not ask for anything.

So you can just participate in the airdrop and then see if there are any problems. If the airdrop is legit then you get free coins and if it is not then nothing has happened.

Best to avoid airdrops that ask you to invest that way its free.

It seems someone else unfriended you because you are spamming. Please be careful. Your account will be under probation now, and if I get more spamming reports, I will have to close it.
