I was thinking of doing LL with Dr. Barinov, so when I messaged them, the woman by the name of Irene Lisovenko (Irene Libra)
messaged me back, requesting the scanned copy of my passport should I wish to proceed with the operation

I'm assuming its for the visa that they apply for you, but I always get anxious when it comes to sending my personal infor to someone I don't know...

How trustworthy is this?
