I'll probably flesh this out more and pose this to everyone on SN, but some combination of i) a giant user influx (maybe 10xing the current size) and ii) people trying to sat farm (like karma farming on Reddit) where people are just mass publishing popular content from other sites for satbait. The combination would be lethal, especially if the influx of people validate the satfarming / satbait because they are treating SN's culture like it's a mainstream content site (i.e., the most popular subreddits, buzzfeed clickbait). One pro of stacker.news is that people with less access to sats with personal capital can build a small stack here, but the flip side of that is that people with lower incomes could see this as a legitimate form of income and try to mass post to satfarm and push out other content.
