Hope this is ok to spread the word.
You don’t need premium either. Just did mine. Or pay the premium $15 one time fee as a thank you to the developer. Super fast, done in minutes. Although I’m wondering if it only deleted the post for the subs still online…. But worth it.
Small update on my comment from yesterday… I checked and 161 comments were back from the 1536 deleted ones. Running shreddit again cleared them out pretty quick though. I’d advise anyone using Shreddit to check after a few days to make sure nothing got restored.
