Hi SEO 4 Attorneys, it could be any thing is this for your site for a clients site.It could be an attempt at negative SEO from a competitor? The thing is people may try to push 100's of spammy links to a site in hopes to knock it down. In the end of the day my best advice is to monitor your link profile on a weekly basis. Try to remove negative links where possible if you cant remove them then opt for the disavow tool as a last resort. 
This is my first time on your blog and I found it when I was reading up on who won the contest at Famous Bloggers. I can definitely see why now! I spent a good amount of time reading and going through all the advice that you've stated in this post since I am fairly new to blogging. I believe one of the biggest hurdles that I will come across when trying to further my blogging experience is driving traffic to my blog. I will make sure to apply many of the techniques you've listed in this post to my blog and hopefully I'll see some traffic! I will definitely continue to read your informative posts. Thanks! :)
Reddit is also worth a special mention here. It’s a cross between a social network and a web forum, which is a traffic source we’ll discuss later. Reddit is one of the largest sites online, and the entire focus of the site is based around posting links and discussing the content of those links. A lot of the content you see trend on Facebook or Twitter is trending because Reddit got hold of it and started engaging with it. However, Reddit is a very tricky platform to use for marketing. You have to avoid approaching it like a marketer, because Reddit users are like piranhas. If they sense you trying to use their audience for money, they’ll swarm you and savage you until you feel like you can’t use the site again. Make sure to read up and take great care before trying to market on Reddit.
Direct traffic is defined as visits with no referring website. When a visitor follows a link from one website to another, the site of origin is considered the referrer. These sites can be search engines, social media, blogs, or other websites that have links to other websites. Direct traffic categorizes visits that do not come from a referring URL.
