It says that once the content is accessed, it vanishes. So, you can have a max 2 day expiration length, but as soon as someone follows the link, it's gone? It's not a bad idea, but it is prone to abuse. I could write a scraper app that would give me all of the active URLs and in doing so would delete any message attached to them. I personally wouldn't, because it doesn't serve much purpose, but if there were a malicious agent, it wouldn't take much to wreak havoc. It wouldn't even be a DDOS level attack, just a simple scraper using minimal resources.
Truly, though, I do like it. I just think that the automatic removal might be a risky feature.
Automatically adding a generatored password to each share site could fix this. Without the password the page cant be accessed and thus wont be deleted.
For sharing, the password could be embedded in the URL as a fragment/query param.
Yeah that’s a really good idea! I was actually exploring something similar too while building this MVP — like adding a PIN or auto-generated password to protect each drop. The idea of putting it in the link as a query also sounds smooth and user-friendly.
This is just an early version I made to test the concept and see what people think, but now I’m definitely thinking about adding this kind of protection to stop abuse. Thanks for the suggestion!
