>> We have our logo on every website with a hyperlink to my site
That sounds unnatural and yes, it very well may hurt your "SEO".
That being said. For sites to which I had access, I removed the hyperlinks.
For sites which I do not have access, should I use the disavow tool?
Could adding a rel="nofollow" suffice?
