I've seen a few posts from more experienced members either using or suggesting the use of the "ignore" button. At first, this struck me as unnecessary, but as I've been finding my feet and exploring the forum more, I'm starting to see their point.
I ain't sure there's any user who has stayed here a complete "Bitcoin circle" of four years who hasn't ignored another user(s). I've a few on my list, mostly scammers and irritable trolls. It's also possible some have me on their ignore list too, for whatever reason they may have. That's the irony of the whole thing. No matter how good a user thinks they're, there will be other users ignoring them too for one reason or the other. It doesn't boil down to only perceived shitposters.
I'm not sure why there are so many posts like this, but my best guess is that it's users either trying to rank up quickly or trying to fulfill their signature campaign commitments.
Of course, ranking up is hardly for shitposters as they don't easily get merited. It's the second option in bold.
