I will check out Fiverr Pro. That still may not address my requirement to screen freelancers. I do not believe Fiverr is intended to be an anonymous platform... nothing in their terms of service states this. I have not found any term that strictly forbid asking for personal information. In fact, the TOS explicitly acknowledges and permits the necessary exchange of personal information. To clarify, I am not planning to request an email as this is not a reliable method of verifying an individuals identity.
To protect our users' privacy, user identities are kept anonymous. Requesting or providing Email addresses, s***e/IM usernames, telephone numbers or any other personal contact details to communicate outside of Fiverr in order to circumvent or abuse the Fiverr messaging system or Fiverr platform is not permitted.
Any necessary exchange of personal information required to continue a service may be exchanged within the Order Page.
If there are other relevant terms I missed please let me know.
