I found an account dedicated to spam posting "enlightened centrist" talking points and pundits. Their name itself is part of the advertising. They even would post the same content across multiple communities, without cross-posting. And not just political stuff, they posted the same meme about 4 times without linking them.
I know this sort of thing happened all the time on Reddit and essentially it was hopeless because of how the corporate power structure worked.
"Politics" and "News" communities seem especially "apolitical" (that is to say Neoliberal) and hands-off "free speech to the end user" about what is posted. I'll frequently see a lame article, sensationalist headline, instead of the first source or the most informative one. Or I'll see a great thread about a great news story - and someone reposts the same content the next day with better timing, and it will be weaker journalism with weaker comments - yet more people will see it. Now this doesn't constitute abuse, but it will be just as permissive of abuse of the system as Reddit was.
I've also seen threads asking about where to find good sources, how to find accurate journalism... without much great advice. It's sort of an acquired skill, but we have the potential to help people acquire it.
Yeah Reddit was the only social media I used, and I think I'm just going to go without.
At least until the seas level, lemmy is all the worst parts of Reddit with none of the good, and I owe it to my mental health to not bother with the hordes of disengenuous bullshit.
If you need a break, you should take it.
Take care.
If you need a break, please take it. Your mental health is not worth sacrificing for random strangers on the internet. I will say it is highly instance dependent, so migrating to a smaller instance may change that experience.
