The community has already discussed with the devs on opening other channels for the airdrop as well and he is open to it. But the current focus is on bitcointalk because most of the crypto world hangs out here. No other reason. Community members have also started working on a marketplace program where members can get airdrops for constructive tasks. As mentioned above, a mechanism has already been put in place to report and slowly remove irrelevant topics from the AI database when making suggestions to improve post quality and topic relevance.
This is a great instance of the good actors of the community helping to eliminate the malicious ones. Kudos for that.
I've reported a good amount of these shill posts from MarineCoin, and I'll continue to do so, but I really do hope that you find a solution that won't encourage spam and shitposts. Sounds like you have something in the works; I just hope it's relatively soon as my fear is that future ICO's will see this as an example of all the shit they can get away with for future campaigns. That's the last thing we need here... A dozen altcoins with hundreds or thousands of users trying to qualify for an airdrop by flooding bitcointalk.
Nope.
