I think a feature to report buyer requests will be helpful. We would be able to report such buyers who are posting buyer requests which are spam or are violating Fiverr’s TOS.
Here is an example:
This guy is asking to communicate outside Fiverr (On email) and I don’t think Fiverr’s review team noticed this. This is just one example, I come across several buyer requests which are either from sellers who are promoting their gigs or from buyers who have no idea of Fiverr’s TOS.
