It may be against ToS, but if Fiverr wants to hold anyone to this they best provide the necessary tools for people to communicate and collaborate effectively. I don't think Fiverr does this.
How are you going to design, develop, and deliver a custom website to a buyer through Fiverr's messaging system only? If the ToS states you are not allowed to communicate anywhere else but the Fiverr website, your SOL (shit out of luck).
I suppose using Adobe XD or Figma or many other design tools that have communication and collaboration built-in are also against ToS. Good luck working in the early 2000's where you send PDF back and forth for reviews and corrections.
You are building a website. Does that website have a contact form? A comments system? Users and member profiles? Message forum? Can't build it. You're not allowed to build this type of software. It would allow communication between yourself and your client.
You are building a website and you don't need the client's email address to sign them up for Cloudflare? Or Azure? or AWS? Or Google to grab API keys? Or to help them sign up for a merchant gateway account?
Where are you putting the source control for your projects? GitHub? That's a communication platform too.
If you literally follow the ToS then you are producing inferior work. Fiverr should drop this to an obvious warning about online safety, and that's it. If an algorithm detects outside contact information, show both users a warning and force them to acknowledge the warning before reading the message.
I have to have Microsoft Teams, or Zoom, or Google screen shares for design reviews. I need to comb through a backlog with my client to prioritize what's being delivered - that also requires communication systems like Monday or Jira or Helpdesk or Github even.
ToS forbids me from doing my damn job.
