Bots stripping watermarks does sound intense, but how often does that actually happen? Feels like one of those rare internet horror stories that gets passed around.
Logan's right that full bot stripping isn't super common yet, but the fake signature thing is a different kind of headache. It's not a bot removing a mark, it's a person actively putting their own name on your work. I've seen it happen where someone just paints over the real signature in Photoshop and types in "johnsmithart" instead. It makes claiming your own stuff way harder because now it looks like it's signed by someone else.
