Some days ago, one of our subscribers shared with us one of the best services with one-time notes (Deep web Pastebin)
Paste .onion is a project raised from open-source. Launched and developed for the coding community especially.
The paste is out of competition in comparison with the sites that we have discovered before. Good functionality with the signature of the authorship and the title, the ability to choose the language of the note, creating a short link to your text. Paste also has an API.
The only bad thing – you can’t delete the note after reading it.
