Just did a cursory search for harm on the YouTube ToS. There is no definition that I saw, but it does say "may cause harm". So my suspicion that anything could be construed to be harmful to YouTube's business is likely correct. Quoted sections of the YouTube ToS containing the word "harm" as of 2025-06-06 17:20 GMT.

What? LOL no, not "exactly". Again the definition is not in question. The question is what the word is referring to.

if they haven't defined it, then legally it is meant in the broadest sense, isn't it?

There is no definition

Okay, I get it. I'm being trolled. Well played, I guess.

YouTube pulled a popular tutorial video from tech creator Jeff Geerling this week, claiming his guide to installing LibreELEC on a Raspberry Pi 5 violated policies against "harmful content." The video, which showed viewers how to set up their own home media servers, had been live for over a year and racked up more than 500,000 views. YouTube's automated systems flagged the content for allegedly teaching people "how to get unauthorized or free access to audio or audiovisual content."

Geerling says his tutorial covered only legal self-hosting of media people already own -- no piracy tools or copyright workarounds. He said he goes out of his way to avoid mentioning popular piracy software in his videos. It's the second time YouTube has pulled a self-hosting content video from Geerling. Last October, YouTube removed his Jellyfin tutorial, though that decision was quickly reversed after appeal. This time, his appeal was denied.

I don't know how to be more clear about this. The definition is not in question. It doesn't matter what sense it's being used. What matters is the subject of the harm.

totally clear. and exactly the subject is the broadest: harmful to anyone or anything

Yep. Most of my favorite creators are on Nebula now.

The ones that aren't get watched on SmartTube or in Brave Browser.

If that were true there would be no videos and no YouTube.

Hypocritical Lemmy.... Preaching (F) OSS and then using Brave....
LoL!

The use of "self-hosting" is a little confusing here. To be clear, he wasn't self-hosting his video. It was published on YouTube, and the guidelines and procedures in question are Google's.

Edit: I'm not defending Google's actions. It's just that the title gave the impression that a video he had self-hosted was somehow subject to "community guidelines", which didn't make sense.

Edit 2: Ten downvotes in less than an hour, on a clarification comment? Wow. I'm disappointed to see that level of targeted negativity here. What rotten behavior.

Brave is open source and using MPL license which is the same license Firefox is using. I am not using or recommending Brave to anyone.

I will flat out shut down any Brave user simply because it tried to push crypto.
No thanks

Not just crypto, they were diverting ad revenue from websites to themselves, collecting unsolicited donations for content creators without their consent, suggesting affiliate links in the address bar and installing a paid VPN service without the user's consent. Don’t forget they had a “bug” in Tor which sent all DNS queries to your ISP instead of routing it through tor and also weak fingerprint protection. Not to mention the political affiliation of the CEO. But it IS open source.

I think ripping DVDs is still technically illegal, even though CSS has long since been broken. It is still illegal to circumvent encryption in a copy protection scheme, even if it's for your own personal use and the encryption scheme has been pwned.

I bet if he didn't mention that his videos were ripped from DVD, they might have left it up.

“how to get unauthorized or free access to audio or audiovisual content.”

In the future, public domain media will be banned for harming corporate profits.
