Sophie Web Stealth Link can be used to evade censorship. If you are concerned that sending links with the untraceable.ch/stealth domain name will put you at risk, just replace the domain with another at your choice.
For example:
https://example.com/#eyJ2IjoiMC4wLjEiLCJlIjoiYUgrNDhISkpBWWhkeFFMc0l0VlIzeFlma21mYlZCOFJ5Zz09In0=
Instead of:
https://untraceable.ch/stealth/#eyJ2IjoiMC4wLjEiLCJlIjoiYUgrNDhISkpBWWhkeFFMc0l0VlIzeFlma21mYlZCOFJ5Zz09In0=
Any domain can be used to replace untraceable.ch/stealth. By this way, a malicious third-party who clicks the altered link will be taken to a valid page, which helps alleviate suspicion.
When sharing the password to unlock the link, explain how to switch out the domain name.
Alternatively paste the altered link directly into the decrypt page.
That page does not check the domain from link, only the "Encrypted part of the link".
