Did you also notice that most Nigerian members here in Bitcointalk earn merit very quickly compared to other local members who have been on Bitcointalk for a long time and have quality posts but still struggle to rank up because they can't earn merit?
Post your comparison, preferably in a chart so it'll be easy to read. Then next you'll need to understand that a gap (if there is any) does not mean one is abusing the system, there is the option that there are not enough merits circulating in other boards/threads.
If your board is low on merits report to the admin that you want a designated merit source. The Nigerian board didn't even have one until few days ago.
Are there cases in the Nigerian community of merit abuse? I'm not being racist here, just an observation. How do they manage to earn merits like that?
This is not an observation but an accusation with no evidence to back it up.
Firstly op why didn't you post this with your main account instead of using an alt?
One is free to make a controversial post using a alt account. But it further shows that this was not a genuine inquiry but a way toncast aspersions.
