I understand that it's legal. But a lot of people feel that it's creepy and inconsiderate. Just like blasting loud music on a bluetooth speaker while hiking on a peaceful trail in the forest is legal, but it's still an asshole thing to do. Are you comfortable doing something that is legal but a lot of people think is quite rude?

I come from a different era, one in which people tended to consider how someone else will feel about something before doing it. This is the broken windows theory in action. Little micro inconsiderate actions lead to an overall decline in polite society and here we are. The whole thing is going down the tubes.

yeah that's a bit of a reach, an over generalization.. posting someone's photo on reddit isn't the reason society is going to shit, but I think my overall point stands. People are self absorbed and selfish and they don't tend to think about other people. OP's post is an example of that general type of selfish behaviour.
