Fortunately I didn't social that much so it doesn't happen too often in my life . not sure if that's good or bad . I feel I have sometimes maybe done some invasive questions online but not to the extreme of your examples. It was probably more light. For example, today I found out one of my guild members in a game burned some of their cards for crypto and then I was shocked and asked why. Then I also asked what he did with the money and now that I look back I guess it could have felt invasive for him depending on his point of view so in a way it's also depends how others take it? There are some questions I feel that could be towards the borderline. The examples you used are for sure invasive though! I'm not sure if I make sense.
As for the answer-avoidance thing I don't think I will blunt but I will just say it more in kind way like hey sorry man that's a bit too personal or something like that. I won't try to make them feel bad for asking. I don't know I hope I made sense
