That time when there was a big propaganda campaign to get everyone to hide inside for a big scary virus.
We probably maybe not really sure saved 0.5%-1% of the population, so it was worth 2-3% of our lives worrying about it, 10% inflation, public transport becoming financially unviable, various career paths literally disappearing, an irreparable political split, education being deleted for a bit, etc.
Thankfully, slightly later on, ~all then got it anyway so now there's at least a critical mass of people who realise this was all a load of shit and I don't have to adblock it by self excluding from all social networks.
I love HN and derive a lot of benefit from it, unfortunately during the Great Scare I found it impossible to stay away from the associated threads.
That sort of stuff seems to have died down now though, so we're good.
If I could just censor any mention of it I'd be much happier, I'd add it to uBlock if I could, heh.
