FWIW, I had a similarish experience with my local Craigslist equivalent (Gumtree)... They had a security breach, which led to my barely-used account being hacked by someone that was posting (I assume) fake car listings.
I reported it to them, and their response was to blacklist me. No great loss - why would I want to use a platform that badly managed. I later worked with one of their mid-level managers from that period, and yeah-it was an absolute shitshow there.
