So I did some brief checking today and what I noticed is that the alts are from the Nigerian community board. Someone is farming accounts through merit cycling and posting in specific thread and boards. The pattern is easy to follow.
This is one of their favourite Threads -
Buy the DIP, and HODL!. If you look closely, you will see similar alts replying to themselves on top of merit abuse and trying to farm merits from merit sources.
This is their favourite signature campaign -
{Resume} Eloncoin Signature Campaign | Member+ [Funds Escrow]I will just post a connection of this two for now (Agbamoni and Dailyscript). Agbamoni is also connected to Richbased and other alts, no doubt.
I would like to add a few coincidences that seem suspicious in my opinion, although I can’t call them with confidence.

Maybe it's the local pronunciation or something else, but if you walk around and observe, not many people use this word.
And they are most used by these three that you found. And also only these;
