That's not algo manipulation that's 'forum sliding' on an internet scale....also called "flood the zone".     In order to shut down pizzagate, what they did was manufacture a shitton of fake news about it and then promoted that heavily and then 'flooded the zone', and then they used the flooded zone (flooded with fake news) to manufacture a reason to BAN the pizzagate subs on reddit, forcing people to come here to voat.    Ok?  SO that information is STILL around and still haunting, 'the zone' (in this case, google search results)
