So now the question itself: Do you pay attention to those users who never send anything to anyone when sending them a merit or you don't care, the main thing is that the post is useful.
I do, sometimes? especially when they already hit Hero or Legendary Ranks, I rarely give to the Legendaries except when it is really needed (means their posts are too worthy of an award)
Also when it comes to newbies and juniors I sometimes check on their Mert History / Post History,... I'm more focused on giving out my sMerits to our Local Board and to its users,...
I'm keeping DdmrDdmr's thread on my track so I could also help the users who only needs a few to rank up. (as of now our Local is back on its dark days, due to campaign restrictions,... an awful fact)...
