Tip: when you find one of the bot spam subs, sort by top posts of all time and block the posters of top posts made in the past 3-4 months
I found the anticapitalism sub is flooded with political news spam. The accounts for nearly every top post in the past 3-4 months seemed to be a politics spam accounts.
A couple of the accounts are probably professionally operated rather than AI bots, since they would have very genuine looking behaviour and engagement, and then suddenly 2-3 pages of spam political news posts within minutes to like 10 different subs. E.g. why is a seemingly Norwegian person suddenly posting news articles about a US supreme court decision to multiple different subs, when the majority of their engagement focuses on local or hobby related matters?
