Unfortunately, there is no such feature built in.
However, using the templates it's not too hard to implement your own. The quick way is to just use a mail to link with the subject= parameter set to the offending link.. e.g.:
Another alternative is to have a custom "post" form for a common "abuse" forum that gets called by the "Report" link. This could be a
servlet or Javascript based HTML only form that would pre-populate the form with the required info (passed via the URL parameters). The action and hidden fields of this form would be the same as the normal post to this forum form contains.
