what happened: Suddenly curiously I start to search Zac finance twitter campaign participants twitter profile. I shortly searched the profile which is accepeted in this reply:
https://bitcointalk.org/index.php?topic=5276327.msg55222873#msg55222873. And found most of the twitter profile were used by someone else. I will not say those are alt accounts. Sometime some dishonest people use other people social media profile to hunt bounty. But there is a chance also some are really alt accounts.
Here is some quoted replies: 1st quote is zac finance participants and 2nd or more is other people's.

I already follow all in this list and wait for them to follow me mostly I unfollow peoples after 7 days if they not give me follow back thanks in advance if these all will follow me good luck.
