Welcome to the Q&A Forum

a trick to  not get personal results is to add &pws=0  to the end of the search url eg https://www.google.co.uk/search?q=keyword&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official**&pws=0**

The best and most efficient solution with any question regarding Moz crawls or tools is to go directly to them with questions (sometimes there's enough unique behind the scenes stuff going on that forum people don't have access to). Their team is great and has helped me a handful of times, quickly and politely.

We do handle it a bit differently - we try to flag near duplicates by looking at source code. Glancing at a few of the instances on your site, I think we're getting a bit hung up by all of the code for the menus (like the drop-down options). It's really heavy HTML, so when only a couple of search results are different, it's making the pages seem too similar. On the one hand, I think Google does know to ignore some aspects, like menus, and the distinct META data does help. On the other hand, search results pages, especially ones with limited or similar results, are considered fairly low value by Google, and you've got a ton of them. By trying to rank all of these variations, you probably are diluting your index quite a bit. So, I'd say that we're being overzealous here, but I'd also say that it's indicative of a problem to some extent.
