Offtopic, but my longtime account on reddit got shadowbanned recently. The only indicator of different behavior was that I posted a comment that sarcastically said "Buy our product!" on an ad post, and it was [removed by reddit]. I noticed none of my comments were showing up, I couldn't message any moderators, and all of my comments were shadow-deleted since the creation of the account. Multiple messages to reddit admins have gone without response.
Really is sad what's happened to online forums. On the other hand, now that I can't engage with reddit, I see how really awful most of its content is. I miss talking on my city sub however.
I use VPN and my email was a passmail alias, which probably didn't help.
I created a new account with passmail alias on VPN, and my CQS was immediately "LOWEST", which means I'll barely be able to be seen anywhere on the site. I created another account from a coffee shop with a fresh gmail account and was rated "MODERATE". Ick.
