How it is possible to know about airdrops before the big guys (airdropalerts, airdropking etc) post them? If you really want to gain something from referrals you need to post them first.

I'm looking for any open source script or maybe free/paid service to use for airdrop. Not something like gleam.io or vyper, but the ones you enter you ETH address, go to next page and have a verification code to be sent on telegram and also your referral link. Anyone knows any script/service?
