Comment Collapsing and Improved Spam Detection
We’ve all seen it: spam comments cluttering a thread, dragging the discussion down. Our latest update, rolling out over the next few weeks,
adds automatic comment collapsing for messages likely to be spam or low-quality.
Mods will see these comments tagged as “Potential Spam” in their community, whereas users will see these comments collapsed automatically, helping to reduce disruption in your community without needing manual moderation.
Early testing shows this tool is a powerful front-line defense, letting you keep an eye on what matters while spam fades into the background.
A big thank you to the communities who helped pilot this experience in r/PartnerCommunities which helped us collect valuable insight into how well the model operates.

As for my own experience:
I have noticed that any comments being made with chatgpt any openai gpt model results in instant account ban, except really old accounts or accounts that are already well established.
Comments that were written by me before adding them to my bots seems to be doing fine.
It was an inevitable step, I noticed reddit becoming very much full of AI low effort comments using perfect grammar and words that no human would ever use in non formal talks which makes it easy to be detected. It will be still possible to comment with AI of course just need a bit more creativity than simply entering a prompt and pasting whatever gets written.
