The only thing I really miss is doing data calculations in Google because I have shitty Internet and I want to know how many hours I’ve gotta let this thing download before I get my bandwidth back.

At this point, the community is clean. So unless more is posted, then you should be good. If someone searched for the community and caused a preview to load while the content was active though, then it could be an issue.

From what I was informed, purging a post doesn’t remove the associated cached data. So I didn’t take any chances.

Not really. You could technically locate the images and determine precisely which ones they are from their filenames, but that means you actually have to view the images long enough to pull the URL. I had no desire to view them for even a moment, and just universally removed them.

As mentioned in my edit above though, ensure you are in compliance with local regulations when dealing with the material in case you have to do any preservation for law enforcement or something.

I’m on 1.18.4, once I deleted the most recent images, the former CSAM posts(among others) became broken images. So yes, it was pulling from local disk cache. Then I took care of the posts themselves after the content was invalidated.

Reminds me of Obsidian, which is what I use for notes. But obsidian isn’t selfhosted. I might actually host a copy of that because it’s cool

You can host a webmail like roundcube or similar. I don’t know if they can be turned into PWAs with phone notifications though.
