I commonly browse all by new, and I block users who crosspost any given article to more than one other community. To me it’s almost always a sign that they actually don’t care about the topic or contents, but instead their own post count and user recognition.
I got downvoted every single time I mentioned reports on Reddit. Oh, well. Downvoting doesn’t hurt. At least maybe I found a few users who stopped chaotic reposting after reading through my described way of thinking about it.
