Also, for general information, from the support section:
This is an advanced feature and should only be used with caution. If used incorrectly, this feature can potentially harm your site’s performance in Google’s search results. We recommend that you disavow backlinks only if you believe you have a considerable number of spammy, artificial, or low-quality links pointing to your site, and if you are confident that the links are causing issues for you. In most cases, Google can assess which links to trust without additional guidance, so most normal or typical sites will not need to use this tool.
And more directly about the uploaded file comments / what's been done to remove links: (Emphasis Added)
Your text file can include additional information about excluded links, as long as each line of description begins with the "#" character (all lines beginning with # will be ignored).
It's optional to include that type of information in the uploaded file.
