All the -70% activity spanking doesn't do much for community building, too early for punishment. The history of airdrop coins being successful without innovation is very poor, there's so much competition now, and when more than 50% of the community realise while they were waiting for direction from the dev they had their pants pulled down and their bums smacked for lack of 'activity', many will stop paying attention here.
For better or worse the dev must lead and show direction, at least at the start. When I see people getting enthusiastic and evangelising an 'unknown' project I smell insincerity and BS. @dev, you lead first and then spank the inactive community members later, not before the fucking project has even started!
They weren't waiting for direction, they just signed in without taking a look if anything is needed from them and without returning. The dev gave a direction. It was to achieve consensus on the first vote, so we can decide when to close the airdrop. Good thing more than 50% of the participants figured it out or we'd still be stuck on the first vote and the airdrop would still be open to new participants. As far as I remember the dev even pushed the deadline 24 hours, to give them one more chance.
Look at it this way. Nobody got penalized. Just the people who actualy participated and helped the vote go through got a +70% bonus for not being a liability to the project.
