Google Disavow Tool: which kind of links do harm and which do not harm my site?

[inlinear]

Recently a guy asked at GoogleWebmasterHelp: Should I be worried if a couple of sites that I don't want to be associated with are linking to me?

In this case there have been 2 porn sites linking to his site... that clear.
But my question is if for example sites like e.g. : http://www.linguee.de

Linguee is one of the best dictionary sites where you can search for phrases and receive common translation examples which are very helpful. Liguee set some links to my site because they take texts usually from multilingual sites to gather examples.
A dictionary site does not have nothing to do with my business but also I don't consider that this might my harm my site?

What do you think?

Yes, linguee seems to be a quality website, apparently well regarded by Google, but I've got 37,000 backlinks from linguee domains (out of 42,000 total backlinks), and my rankings have been dropping during the last months (as the number of backlinks from linguee has been growing steadily) .

Should I disavow these links? What do you think?

I agree with redfishking, as long as the links are coming from a quality, authentic website they should not hurt your rankings. It is only when there are a number of links from one site or the website would be considered low-quality that it can do potential harm. In such cases I would be inclined to recommend using the disavow tool, however if its a minute amount of links from a credible source I would not worry.

A link like this shouldn't harm your site, and if it is a follow link, could be helping you in the rankings.

Google does not expect every single link to a site to be perfectly relevant and authoritative. There are bound to be a number of irrelevant links to any site, because anyone on the internet can post anything at any time. This site in particular seems to be a high quality, useful site, and even though a dictionary is not relevant to your business, the language you are using on your site IS relevant to text translation.

Unless you are getting many (read: hundreds or thousands) of links from this site, it should have a negligible or slightly beneficial effect on your rankings.
