Seriously, 600 twitter guys, I guarantee the real are only 100-200 people, others are alt accounts. RIP TW and FB campaign, you see signature campaign, 100 people, the very accurate real people join this project.
Twitter campaign is a trouble. We don't know how to track every repost cause TW shows not more 100 retweets per tweet. With FB we very accurate: all spammers and clones declined)
the only way is to be very active and trace spammers immediately. or hire a twitter campaign manager. who can protect your twitter bounty.
BTW. Inchain will be another great ICO after ICONOMI. I am having this feeling from right now.
