but you can report to the campaign manager if they joined in one bounty campaign that prohibits multi accounts
and you can also expose them by posting here Known Alts of any-one - A User Generated List Mk III (2018 Q2)
unpack seems like he/she is not joining any bounty that's why it is vague that he is the owner of these two but the thing is, these two accounts used unpack's twitter for about several times. So, does it means he is involved too?
By the way, AltT25 and Nafta012 seems like haven't been active recently since April.
What do you think? Should I make report for this now?
