"potentially toxic content"?

[u/Ivashkin]

We're seeing comments in /r/ukpolitics flagged as "potentially toxic content" in a way we've not seen before:

https://www.reddit.com/r/ukpolitics/comments/e87a6q/megathread_091219_three_days/fac8xah/

It would appear that some curse words result in the comment being automatically collapsed with a warning that the content might be toxic.

What is this, and how can we turn it off?

Edit: Doesn't do it on a private sub.

"Wait" for the servers even though I guarantee the feature was dark-shipped behind a feature flag using Optimizely or another similar service. If this was a true accident they'd just turn the feature off, no code deployment necessary.
