Just want to clarify that in-content links in a guest post are considered unnatural by Google.
We are in the process of removing unnatural links from a client's website and it has several such "in-content" links that has keyword rich anchors and so definitely not natural
As for the OP's question, if you have tried everything in your capacity and still can't get those links removed, then simply list those blog URLs in a txt file and submit it to the Google Disavow Tool. Also it would help if you could show a documentary evidence of your attempts (either in a spreadsheet or via an email account) in getting those links removed while filing your reconsideration request
