Is there a person on playstation 3 with 100 platinum Trophies?

It's highly unlikely that someone has 100 platinum trophies on PlayStation 3. Here's why:

* Limited Number of Games: The PlayStation 3 era had a significantly smaller library of games compared to later consoles. This means there were fewer opportunities to earn platinum trophies.

* Difficulty of Platinums: While some platinum trophies are achievable, many require a significant amount of time, dedication, and skill. Achieving 100 of them on a single console would be incredibly challenging.

* No Official Tracking: PlayStation doesn't publicly display the number of platinum trophies a user has earned. While there are third-party websites that track trophies, they are not official and may not be completely accurate.

Even if someone did manage to get close to 100 platinum trophies on PS3, it's highly probable their achievement wouldn't be widely known or documented.

While it's not impossible, it's extremely unlikely anyone has achieved this feat.
