This one is not an airdrop : Ruzzy Token Airdrop Campaign (350 Ruz) they want you to send them ether and call it an airdrop.

There are scams for sure, some of those I signed up for are just gone, they take your data and go.

I have put the ones at the bottom that are broken or strange, not sure if they are scams but these are the ones I did.

HI all, I am posted this after discussion with the moderator about removing all referral links.
This is my first post to this forum and I hope you enjoy it. 
What I think is missing in the cryptocurrency world is the free sharing of code and ideas that is part of the open source world that spawn bitcoin.
Many new people in the space are not interesting in open source or what created bitcoin.
So I would like to invite you all to share the airdrops you find in this new github page that I am building.
Basically it contains a list of airdrops, free tokens, and bounties without any referral links. You are free to fork the page and add in your referral codes, but the main repo will not contain any.

Also I am containing a section on actual coins received, and would be very interested to hear from more people who have actually gotten anything.

Also I am listing finished airdrops and broken pages to share that info.

https://tpoonach.github.io/awesome-airdrops/ is the site and
the git repo is https://github.com/tpoonach/awesome-airdrops
