Um, I'm totally at a loss here as I neither get your exact problem nor your question

What is your native language? Maybe it would help if you'd ask your question in the local forum

Lol, I'm not very good in English, but I never thought I was that bad.
For example this airdrop, using a docs.google, like many airdrops do (but not all of them) :
https://docs.google.com/forms/d/e/1FAIpQLSd_gStvrOb8RjBP0lMNGL4Yq7A_HqMcTgWN2jF_Jbe39bJw2g/viewformYou fill out the form, then it's over, you get tokens for that particular airdrop, but when there is a referral program, how to do you share the form? what referral link do you share ? We get no referral links to share. Yet, i still see this airdrop being shared by airdrop channels, so it has to have a referral system. How do we get it ? I can't just share the url adresse like i've just done for the one above (how will the company airdroping its tokens know it's me who shared the link?)
In most of the cases, airdrops with referral program comes in different structure:
Sample 1: Participants have to invite users in the Telegram group (of that airdrop). Invite people and shows proof to the one who will be assigned to check your credentials. There are different ways to show proofs so it depends on the instruction.
Sample 2: Participants will fill up the form directly at the website and not on the Google form as obviously no codes can be given here. In website registration, there should be a kind of referral code at the end.
Now to minimize our works here, would you mind telling us here what airdrop you are talking about that have a referral program but no way to get a referral link?
