I am concerned about the links pointing to my site. There have been an additional 273 dodgy links added in the last 2 months for unknown reasons skewing the linking domains by DA to mostly 1-10\. Could this be a negative SEO campaign?

Dodgy links, possible negative SEO campaign.

it is certainly possible depending on the content of the website. I have issues with an individual producing links from very disreputable sources. Essentially if the contents one these:

• Link to Fireams
• Link to Gambling
• Link to a page linked to your site that is a clone as to cause the content duplication issues
• Adult XXX content

It's a very likely possibility. especially with a questionable suffix like a tk or nl for example. I wouldn't worry about it, Google seems rather savvy in not including garbage like that in your overall score. Just make certain you don't link back to the content obviously. There is always the option to submit a disavow txt file if you think it is impacting your rank, but I doubt you have to worry.
