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 mean, you’re not on my blocklist.
I actually don’t typically block people who are clearly looking for help or input on their work. That’s just something that is gonna happen, and I’d prefer people find the assistance they need.
