Several accounts are actively involved in these threads. It's not hard to guess that this is part of a small bumping farm.
Yep, all those accounts mentioned are indeed part of the bumping farm working on all those four threads that you mentioned (Aladdin Exchange, SOCIETATIS, CRP and Chaingateway) so they have been added on the list. I can't believe that this thing is still going on, how clueless those that are hiring these guys must be if they keep hiring them? As someone said earlier, scammers scamming other scammers.
Regarding those 4 accounts, they have another thing in common, and that's the source of their merit, now banned account
kpcian. So, we have here four accounts that are working on the same threads and all of them got their only merit from a single account, that is banned now. Another coincidence? I think not.
