I think the accounts that publicly supported JustinSun on the steem blockchain are going to be excluded from the airdrop. People who supported him on other platforms, you can't always pinpoint them to a specific steem blockchain account and thus you can't exclude them from the airdrop based on assumption that, person @x on twitter is the owner of the steem account @x, for example.
Now which accounts...well a few accounts from a certain community might miss out, I guess I don’t need to mention which one lol 😅
Edit : Also just found out anyone who voted for the sock puppets will also be forked out. Even if they change their votes now, the transaction history will remain so they will be forked out.
oh interesting, thanks for the info! I honestly wish they would publish a list and be more transparent with it.
