Thank you lovesmayfamilis, this is the kind of help that I was asking for. I think we might be into something here. I also see a similar pattern between the N.O and Zerato accounts and it is that at the beginning there are posting gaps in the post history but in the case of zerato I noticed that when he had enough activity and merit to move up in rank he stopped posting until he could get to the next rank.
Probably Zerato, N.O, cryptoWODL and AirtelBuzz are either alts or part of a farm, although we have no conclusive evidence.
We have no evidence. FYI, some of the accounts you mentioned above have been warned previously by our local members! Also, if you take a look at their merit exchange history, you'll notice most of the merits are from a certain thread, for example, the "WO" thread, or "Buy the DIP, HOLD" thread, or certain games and contest threads. They are clearly using a premeditated plan to rank up, buttering up legendary members on the way.
