PowerDeleteSuite. I used this when things went hot with Reddit. You can even edit your comments before deleting them, best part for you, you don’t have to delete them. (Hopefully Reddit haven’t countered this).
Look at the issues and you will notice it only works on comments visible from the profile page and that not all are visible. It appears that someone made a python script to solve this problem but that you need an API key to use it.
What’s the best method to mass edit my comments?
