At the height of it, yes. It filled up the front page every single day and made the site absolutely reek.
It’s what made me stop browsing /r/all, drop off most default subs, and stick to only my subscribed subs. Brigading and spamming is the whole point.
And it was absolutely a case of negligent opsec.
I suspect what happened is that I posted pictures on reddit that I also posted on Facebook. A reverse image search links my reddit account to my facebook account, and therefore a real name and name of city. With that, the rest is public information.
It was a wakeup call that the internet contains the best and the worst of humanity, and the worst will come after you at the earliest opportunity.
