Either you have privacy for _all_ users or you have none. If you accept
lesser privacy for some users, at random, several stat aggregation
schemes are possible. Downside is that you have to decide that some
users in fact have less privacy from time to time.

Attacks on Tor is way outside the scoope of this discussion but it is
possible for this kind of sites.

You can run a script to inspect the dom-three for external urls and
report back if something suspicious are found but it is highly error
prone and can easily be defeated.
