I'm far concerened as to why on earth you added the words "most likely" to your title? 😂
1. Why do you care? 2. A 100 year old wouldn't be on GAG they're far more experied than any of us and I don't think they could use the internet 3. I've never seen members with accounts like that disappear (close enough) @mistnigqa808
I'm assuming it's becuase not everyone wants to share their age while also not wanting to go anonymous to answer things. Some people also just like to answer questions in trolly ways. I believe choosing Antarctica as a location is even possible on this site.
Once upon a time the site had an age range displayed instead of everyone's exact age and I actually kind of miss that.
