The three places your words live
To understand what "delete" can do, you have to know where a comment actually exists:
- On Reddit - the live copy, the one you control.
- In caches - search engines, Reddit mirrors like Reveddit, and scrapers that keep their own copies.
- In archives - the Wayback Machine and similar, which snapshot pages and keep them more or less forever.
A delete acts on the first. The other two are the honest part of this conversation.
What a delete actually clears
Deleting removes the item from Reddit: your profile, the thread, the API. Karmdit then runs its 7-day verification to confirm it's actually gone from public view, because Reddit sometimes lets a deleted item linger. For the live copy, delete works.
Delete is total on Reddit. Everywhere else, it's a probability.
What archives keep
If a scraper or archive captured your comment before you deleted it, that copy is theirs. Reddit-side deletion can't reach into a third party's database, and no honest tool can promise otherwise. Anyone who claims to "erase you from the internet" is selling you something.
The good news: most content is never archived at all. Archives and scrapers are selective - they favor popular threads and things that changed. The average old comment simply isn't worth anyone's storage.
Shifting the odds
This is where overwrite-before-delete earns its place. By replacing the body with a placeholder before deleting, Karmdit changes what a late or edit-triggered scraper can capture: the placeholder, not your words. Many scrapers snapshot on edit - so overwriting first turns their own trigger against them.
It doesn't rewrite history that's already archived. It does mean that from the overwrite onward, the recoverable version is meaningless.
A realistic bar
Here's the honest standard to aim for: not "erased from all of human memory," which no one can deliver, but "not findable by a normal person doing a normal search." That bar is very achievable - delete the live copy, overwrite so caches degrade, verify it's gone.
If you're facing a determined, resourced adversary with pre-existing archives, that's a different and much harder problem, and you should know it. For everyone else, this is enough.
