You stumbled into signature spam hell, where people with poor English post similar topics to post in.
It has become horrible indeed. However, there are still some people that are signature campaign participants and make genuine posts.
for sure they are, but they slowly stop posting or visiting this board at all. I would say, that signature campaigns are actually the reason, we we had threads like OP mentioned (and why it seems, that bitcoiners are dumb)
is Staff aware about this? discussions and post quality significantly lost value over years (you can also see a difference, right?) and it is now more than less earning platform for signature whores from third world, where they already have net access...
