I don't see what the problem is with the OP using an alt account to say this. Alts are explicitly allowed on this forum and originally the idea was that you could use them to say controversial things that you don't want to say with your main account, so I think it's fine for the OP to create an alt.
I don't agree with what he says though. The merit system is not perfect but it is very good and it improved the forum a lot compared to the ranking system when I registered in summer 2017. With it, if you are a good poster you will get merits, and if you don't get merits then your contribution to the forum is not good enough.
Merit distribution isn't really that fair and I'm assuming that they are building their own sockpuppets to solo out and milk out signature campaigns that requires accounts that have lots of merit counts.
Your assumption is incorrect, and I don't deny that there may be some isolated cases, but as things stand, it is better for them to concentrate on a single account that will end up paying them a lot, in some cases with custom deals, than to have several, because the time they have is limited and the quality inevitably suffers if you have several accounts.
Look at the requirements to enter the Green Zone of the campaigns managed by Royse777 for example.
WHAT IS GREEN ZONE?As a campaign manager, my job is to provide the BEST VALUE of the money a project spend on Bitcointalk marketing. Besides, it became obvious that even though the forum rank of two or more members are the same but their overall performance regarding post quality, number of posts they made so far, merit vs post ratio, merit vs activity ratio, acceptability of their opinions in discussions, DT status, accuracy in the feedback leaving habit, correct practice of trust setting, forum socializing skills, knowledge about bitcoin and any subject in topics they engage, influence over others or ability to organize groups and lead a gang (LOL), individual acceptance in their own gang members (LOLx) - all are different. There are many more parameters we consider to pay a campaigner that bring the BEST VALUE from him/her.
So, it's not just about merits, it's much more than that.
