Is it against the terms of service on Fiverr to offer beta reading gigs for different genres, like one for young adults, one for fantasy, etc.?
In my opinion you might or might not get away with it - but a good seller doesn’t take chances like this.
Basically you are offering a beta reading service. Whatever way you dress it up, it is the same service - regardless of the genre.
If someone reports your gigs - then they will be taken down and you will likely receive a warning.
It really is not worth the risk of building up a gig or gigs to risk it or them being removed.
We see so many people moan on in the forums about how their “best selling gig has been removed” - and then we discover they broke Fiverr’s TOS. No sympathy.
