You are still affected by this. Upvoted posts and comments tend to show up earlier in your feed (except if you’re sorting strictly by new). Some instances may even decide to auto-hide content below a certain threshold. So a politically motivated group or even just a person with a significant enough bot-army could manipulate post visibility and kinda soft-shadow-ban people they deem unfavorable.
I could swear I have built all of those in Spore at some point.
