No. In my experience is hasn't been a concern and that experience is really relevant to PC.

I don't have any concerns, but obviously each person should decide for themselves whether fear-mongering [see headlines with words like "SHOCK"] holds a lot of water, versus just common sense.

So, that's all.

ETA: Actually, that's not all. If your concern is about personal information shared here- specific text- that is not applicable. I am not sure it is helpful to pursue this discussion as you are, zinco, because I'm not entirely sure you understand what "data brokers" actually share or trade.

The way you are addressing the concern is giving a very wrong and potentially harmful impression. Not really beneficial to a place where people are looking for support.
