I no longer use the internet much as I used to.
Just use it sensibly to protect yourself from those situations you linked above, & it'll be mostly, if not 100%, fine.
Unfortunately even with proper precautions taken there are idiots out there who will literally track down your IP to the last digit and find where you live and plan whatever. You'd be amazed how easy it would be to spot people at least here in the US.
That's why I said "mostly."
An overwhelming majority of net users don't encounter the aforementioned situations, which affect only a tiny minority, & you can also greatly reduce your chances of falling into that minority by acting sensibly. Nothing is guaranteed, of course, just as one could be killed in traffic accidents (& many people are killed in them around the world everyday, too, but they still constitute a tiny minority of all road users).
