It sounds like you're addressing a troubling trend of fake animal rescues on YouTube, where channels stage dangerous situations involving animals to gain attention and appear heroic. The channels you mentioned—KM Animal, KM Daily, Happy Dog, and The Rescue Journey TV—have been involved in creating these staged scenarios, with KM Animal being particularly notorious for its shocking content.

Here's a summary of the situation:

1. KM Animal: This channel was exposed for staging a video where they pretended to rescue a puppy from a supposed attack by a dog. The video involved severe animal cruelty, and the channel was rebranded as KM Daily after facing backlash. Despite the name change, KM Daily continues to post similar content.
2. Happy Dog: This channel is also involved in staging fake rescues. While specifics about recent developments aren't detailed, it's part of the same troubling trend.
3. The Rescue Journey TV: Like the others, this channel has been criticized for its staged rescue scenarios. There have been new developments with this channel as well, though the specifics aren't clear from your summary.

These channels not only cause harm to animals but also contribute to misleading the public about the reality of animal rescue. The continued activity and rebranding of these channels highlight ongoing issues with content regulation and enforcement on the platform.
