Ah, shit. I know I just sent out a bunch of merits for posts made in that thread, and I haven't checked but I do think they were made from one or more Nigerian members. Granted, they weren't bad posts at all (else I wouldn't have merited them), but I really, really don't want to get taken advantage of more so than I probably am when doing post history reviews.
I am not stating any local board specifically but without a shadow of doubt I have two in mind that I think have a significant amount of account farms. They have provided a lot drama in the forum over the past couple of years and people can come to own conclusions. Having said that, you are far too generous with your time and merits therefore you are a target for those with account farms trying to rank up.
I wonder if people are watching my merit-giving activity or if it's something else that's more nefarious.
They most probably have concluded you are too generous therefore are trying to get as many merits out of you as possible.
