Hello,

I'm aware the "a better community for my post" is not working correctly, but wanted to give a specific example of this misfiring so that Reddit could fix it.

On August 7, 2026, u/ModCodeOfConduct announced the r/Avast subreddit was being opened up to new moderatorship (is that a word?) after being abandoned by its previous owners. Avast is the sub-brand of a company called Gen Digital and they make the antivirus engine marked under different names by the companies other sub-brands (

Hello,

The expiration of the 2011 Microsoft KEK CA and the 2011 Microsoft UEFI CA certificates at the end of June 2025 has caused problems with Secure Boot on computers for various folks who have not been able to apply a UEFI (BIOS) firmware update for various reasons.

Because the steps for updating firmware vary not just from manufacturer to manufacturer but between individual models as well, it can be difficult to provide specific assistance and guidance in updating your firmware unless the person helping you has the same hardware.

Below is a list of manufacturers, their Secure Boot certificate update guidance, and links to their support forum(s) or subreddit(s). You may wish to try as

Hello,

I came across a subreddit which has been created for the express purposes of stealing a commercial service. How do I report this subreddit?

From looking at https://www.reddit.com/report there are options to report individual messages and redditors, but not an entire subreddit.

Hello,

I moderate a couple of troubleshooting/support reddits where redditors often upload pictures or videos of their computer problem.

For whatever reason, these graphics often appear at a 90° angle when viewed in Reddit.

This makes it more difficult to read, resulting in less interaction with redditors, and a longer time to receive an answer to their question.

It would be nice if moderators had the option to rotate a post's image or video in 90° increments (90°, 180°, and 270°) so that it is viewed right-side up. This could also make it easier for Reddit's AI to scrape text and recognize objects in them.
