While people get rewarded for them, they will continue and spawn more attempts. Some of the money being put into these posts by people that should know better is quite amazing.
People will always chase rewards by copycatting and while shite gets rewarded that is what will get Xeroxed.
Is it really worth it though at the end of the day?
I think no but as you know, most don't think at all. They act without sensitivity or consideration of the environments and feel they are acting well.
The ones that know better act from a position of greed, even if it is not in their own best interest.
But, I work hard for little reward in the hope it will be recognised, so what do I know? :)
