Whilst I can't see a way of filtering the last one, the first two
could be tackled on the server-side. I say "could" but would I really
be a good idea to parse the referencing url to check the link is
actually there?

Duplicates could be checked for though.

Unless you pingback the wrong url by mistake?

It is rare but it is possible (for me, at least) to link to the wrong
url on someone's weblog (usually the home page instead of the
permalink). Afterwards, you can modify your post to point to the
correct url, but you can't modify what you've pingbacked.
