I've never had to do this much, just a few cases. However I'm also super-cautious not to view slop on my main account, instead doing so in a private tab.
So not feeding the algorithm seems to work as well.
Yeah, if you decide to check out slop once your feed will be drowned in spam. Similar to how I looked at a couple more pro-Russian videos to get s nuanced perspective and then my whole feed was filled with conspiracy shit and nazi stuff.
