I really can't imagine it would Nick. Have you noticed any reduction in the SERPs that are making you concerned? Google, obviously, have no guidelines on this, so perhaps add in a way to change the units manually, if you wish?

Excellent stuff. Glad it helped

So you just want to disallow the /review/ element?

*Disallow: /review/

I am pretty sure the wildcard will work.

I would use the Robots.txt tester in Webmaster tools to try it out first before committing to any changes. This will tell you if it works and if so, if it's blocked successfully.

You then try the URL without the /review/ element on and make sure it passes.

One additional point on disavowing, when looking at sites, don't automatically disavow a single bad link as a page - if you think that there is a chance you could see a link from a site you never want a link from, disavow at a domain level. Leave page-level disavows for those links where you might just not be happy with what you have this time.

Patrick has covered everything you need to know here, and most importantly, it wont hurt your rankings one bit.

Absolutely - would be worth adding Anchor Text into the mix as well.

You missed a biggy Patrick - is it dofollow / nofollow

Hi David,

Spam scores like this are based on algorithms, so without seeing the links, it would be very difficult to advise correctly on this. There are other factors to take into account as well.

Would you like to PM me the information and I would be happy to take a look for you.

I have sent Dan from Screaming Frog a tweet for you Fred. I'm sure he will be along presently
