As a relatively new user I was disgusted by all the abuse. However I don't agree that making the airdrop more exclusive would be better for the community in the long term.
I definitely agree that it would have drastically reduced the abuse in the airdrop, but people like me would not have been able to participate. And I'm sure there were at least a few real people gained thanks to the airdrop.
There will always be those that game the system. That just highlights the need for more people like you who spend the time to weed them out. You seasoned people understand how to deter these abusers, and you're effective at it, without having the tools of a fascist platform like failbook.
It was exactly because of users like you, we decided to start out as we did. Obviously, we knew exactly what would happen, but had we started out more exclusively, it wouldn't have got the attention it got. When the abuse became too much, we made the change. But hopefully, we got a lot of "real" users on board too by doing it the way we did.
I really hope that this airdrop is a huge success. It will attract more projects to organize such contests.
