Is it illegal to create +18 content with deepfake technology?

[DuuNSo]

It might be a little long, I'm not sure if it's a crime or not.

Let me tell you the story:

One day I was with my friends. The conversation inevitably turned to sex most of the time. One of them mentioned deepfake, I think it's called deepn**e. I got curious and did some research. Of course, being naive, I clicked on the first site that came up. I clicked on the upload photo button and opened my gallery. Just out of curiosity, I decided to use a random character's photo from GTA Online. The character was a gaming avatar, not a real person, of course. Then I uploaded this picture and, as you can imagine, it created a nude image of the character. I have no interest in such things, so I immediately closed the site. But two questions lingered in my mind and I want to ask them:
- Would using this site constitute a crime?
- Is there a possibility of my accounts being hacked?

Note:
- I accessed the site in incognito mode.
- The VPN might have been on, but I can't remember.
- It's been a few months since the incident (I'm worried about my account being hacked because there are many games on it)

It would greatly ease my mind if you could help with this.
