Sorry about this late response. For the theft, I recommend you pull
ALL of your mods down from YouTube, since this is not the first time you mentioned theft occurring. Last time was in 2022.
As I mentioned, you should swiftly pull all of your mods off of YouTube if they haven't been already. I doubt Google will take any action upon this.
A small recommendation I can give is to use a
Mega account. Mega is highly encrypted and private. The only way to access your mega is if you directly provide a link to the download. This will help you keep track of who has what when sharing with people.
