So what's your solution?
I say if you don't want anyone to find out your IP address, use Tor,
that's what it was built for. Then if you accidentally click on a
link and wind up at an attack site, that site's administrator has no
way to figure out your IP.
That only solves the problem of leaking your IP address, of course.
The larger problem of being pseudonymous is essentially unsolved.
With enough effort just about any pseudonym can be cracked.
If you're worried about someone finding out your IP address, then yes,
Tor is probably your best bet.
