I suspect, if they are Alt accounts from the AdkinsBET site, chances are that the accounts have been bought and sold, as said by: @JollyGood: https://bitcointalk.org/index.php?action=trust;u=1016855

I saw at the beginning some of the accounts were used by Indonesians.
Currently their posts are mostly on gambling boards.

If I glanced at one of them, let's call it a name: @Cacingkemi.
Also has several other Alt accounts.
For example:

I think they bought it on purpose, just to install the AdkinsBET sig.
Rather than paying participants per week in $$$.
Guess.
