Do you trust members of SimilarWorlds who don’t have any friends, hide their friends, or no post but still send you messages or talk to you in private

I honestly don't know how to add friends on here and I've never even thought about it, if I have any saved it's probably by accident, I'm still learning to navigate like sometimes I try to respond to a message from someone and I end up on their page rather than in my inbox so I pray that people don't think I'm stalking, if I end up on your pages I probably got lost trying to do something totally different, so I couldn't tell you whether mine is hidden or not. There's just a handful of people that I talk to on a daily basis and I've never looked at their friends list because I feel it's not my business.
