The first thing you need is an account with a service like furl.net
this will give you the possibility to keep a copy of the page even if
it is cleaned up in the page and/or in Google
and without keeping copies of these pages all over the place

the second thing are the hacked pages
It would be a bit stupid that you would do it yourself

the only good database of hacked pages is zone-h.org
but since more or less half a year they have been going offline
and online and are cleaning or destroying their archive-database
of hacked sites faster than you can keep pace.

Seeing the number it makes no sense trying to keep a copy of all
the hacked pages in the world. You have to concentrate on something
specific.

I have for example a gallery of hacked .be sites since nearly a year
be-hacked.skynetblogs.be

As you can see I have changed from putting up screenshots to furl
It goes much faster especially if you use the furl toolbar (no popup
if you have many tabs open). Afterwards you can in the tools of furl
make an RSS feed for your website and in the advanced function of it
you can specify the section. For example all hacked sites are put in
the furl category hacked.

You should also be sure that your machine is well protected
and clean it afterwards with different tools because one way or another
stuff always gets passed through - so now you understand why so much stuff
is not detected by the traditional protection tools.

When Zone-h.org is down, you can go to Google
site:.uk for example and 'hacked by'
You will have to open the sites because not all pages are actually still
defaced, even the cache is old.

after a while you will also find different other keyterms like
names of sites of hackergroups, emails, names and so on

If you build one, give me a tip and I can link to it

Did I say that you shouldn't publish your own hacks ?
