Obviously a few years ago, the API changes caused the reddit community mods to strike, and caused a mass-blackout of most reddit core communities. Eventually Reddit removed a handful of mod teams on some notable subreddits and caused the rest to chicken-out. But it did birth the Fediverse properly.
I suspect Reddit will make another step at some point which causes another comparable exodus. This time, if they do, the Fediverse is far better developed to handle it. What do you imagine it might be?
It’ll be when they cave to ID verification to access the porn. Whoever doesn’t jump ship then will then do so once the porn gets banned completely.
Either way, where the porn goes, so goes the traffic. VHS, DVD, the internet/streaming. All major shifts in traffic were porn related.
