I've given up reporting obviously scammy (and sometimes blatantly illegal) adverts, links, and profiles, to facebook. The canned “doesn't break out community rules” responses or no response at all, confirms to me that a large part of the point of facebook is ripping people off and facebook know it! I've even stopped commenting on the adverts with a list of red flags to warn others, because that just makes facebook show you more of them (if you've engaged with one, you might be interested in seeing others!).
