I've suggested it before (and I'm not sure if you've seen it): how about an airdrop to existing Bitcointalk user accounts? You risk airdropping on account farmers, but if it's related to Merit received and account Rank, you can exclude many spammers.
That would be fine if it could be automated.
Scraping the forum can be automated, but it's on the edge of the forum rules if people are required to post anything for an altcoin giveaway. Then again, the Altcoin Bounty thread is used for nothing less than that.
If it's required to have received Merit, the number of qualifying users is limited to just over 10,000.
An ideal solution would be where users can confirm their account ownership to receive their share. Any community input on how to do this?
What happened to the GBYTE trading volume? It dropped under $100k!
