As @lovesmayfamilis said, from the address they use, their new transaction connects account 1 to account 4 and vice versa, there is no doubt that all four are Alt.
Looking again to see if they cheated in the same campaign, the answer is yes, they cheated.
The four accounts participated in an active campaign managed by @julerz12, all four of them cheated in the sig and Twitter section of the campaign.
The proof:
Campaign Name:
[BOUNTY] Popkitty - Blockchain Social Media | Bounty Campaign | Join Now.Their evidence is recorded at:
spreadsheets
So here are the accounts:
Justian1993
santosmichael
shade jenn
liemfrans
The evidence above is clear that they were involved in cheating in the same campaign and are still active.
OP, you can PM @julerz12 to tell him, there is a fraudulent Alt account.
