We all know that there is nothing wrong with having an alt account, as long as you don't break bounty campaign rules and exchange the trust or merit between your alts, but those two accounts did the latter. It will be interesting to hear an explanation for this.
As it can be seen from hulla bpip screenshot below, they exchanged quiet a few merit between themselves. Hulla sent 25 merit to posi, and posi sent 12 merit back.
