[SpamCop-List] Bogus Spamvertised Web Links

[spamacyde]

Is it possible  for a spammer to provide a link that involves the IP address
of a  legitimate web site if they want to mess with the spam recipient or
host of that web site?

If the answer to the question above is yes, when spamcop deobfuscates links
in a spam message, does it make an attempt to verify  whether the links
point to a "bad" website as oppossed to a "good" one?

If the answer to the second question no, what do I need to do to protect
myself when clicking on a link to verify that it goes to a "bad" site ie one
that is trying to sell me potions as opposed to Fred's blog about pine trees
or no site at all?

Thanks.
