What do you think about saying "I love you" to random people online?
Depends on the context, but as a rule, I don't recommend it.
Deep down I'm of shallow relationships.
If something is bothering you online, you should just move on to some other task so that you don't take personal offense to it. Don't be so upset over the actions of others since you can't control them.
But what if it's some evil?
On the internet, no one is in immediate harm. Best to focus on the tangibles in your world. You can't police the internet.
