Guys. I'm constantly crying in bed at night because I can't find videos from models I used to watch. Those videos are from less than 10 years ago.
Yeah whatever is on the internet stays on the internet, but you severely overestimate how easy it is to find older stuff.
Some videos do disappear, there are also laws to make that happen. And if they aren't made to disappear, most people will have moved on to newer models, websites will have closed and new ones will have opened, and in that timespan there will be a trillion new videos under the "cute asian solo" search terms.
If she retires, this kid will possibly never find a single video of her mom. If she doesn't, I'm pretty sure she will spill the beans pretty early on and the kid will know how to avoid her videos.
