What about a scenario where a project after requesting for such payment from participants actually airdropped but to just about 15% of their participants out of a 100% that made that TON payment task. Can that still be regarded as some form of scam? since the notion has been that most of these airdrops that request some fee to be paid don't usually fulfill their promise.
Yes, I will still regard them as scam because if they received TON from 80% of participants, then they should distribute to all those people that paid that fee. If they would only pay to 15%, when then did they accept fee from everyone? They need to return their ton back if they will not give them any reward.
