Just to be safe, make sure to also copy the url into a note app, or some other location where you'll never look at it again.

Redirect it to /dev/null, that way you'll never see it again, so won't feel guilty:

$ cat this >/dev/null

Bonus points for redirecting standard error to standard output:

$ cat this >/dev/null 2>&1

Now no one will hear the screams ...

Why not buy an copy and put it on your to-read shelf for the next couple of months?

Months? How about years? And then start it, step away for a year, come back and start it again, then step away for a year, come back and … ?
