Artist starts using huge watermarks in illustrations to avoid AI

The fear of having one’s drawing style copied by an AI, allowing anyone to create artwork based on it, is leading some illustrators to adopt tactics that leave many of their fans perplexed. Take, for example, the hentai artist Eunos.
Japanese users have been commenting that the fear of having their art used to train AI has led Eunos to place enormous watermarks on his illustrations, making it harder for fans to enjoy his work.
Some examples:

I even tried to see if I could include more of his artwork here, but it’s not possible. He creates many explicit illustrations, but it’s noticeable that he is now adding a huge watermark.
The reactions:
- By the end of the year they’ll probably recognize watermarks and exclude them from training anyway
- First of all, you can’t even get off to “deformed breasts”
- It’s ridiculous to do this for fanart
- Wouldn’t it be better to just use AI?
- If you draw in cubism, AI still doesn’t understand cubism
- Apparently this doesn’t really affect AI much
- It’s already too late. The training is already done
- Does this “do not use for training” label even do anything?
- There is no legal protection and the watermark can be removed, so it’s basically useless
- Removing watermarks is itself problematic
This kind of drawing is already easily generated by AI anyway
