I was a little confused about your questions, so I took a look at your profile. You asked about what can happen to a seller’s profile if they cancel an order, or if they are unable to create a logo for a customer.
I’m going to guess, but it sounds like you are having trouble with a current buyer. One who may have thought you could provide logo service. And they may be unhappy with what you have delivered so far.
Here is why I guess this. Your gig images are other people’s work and not your own. Not only is this a ToS violation, it’s also bad business practice. This could lead customers to think you actually did those logos, and I would assume they would ask to cancel when they found out you didn’t.
Please don’t open a Fiverr gig with stolen materials. If you are a capable artist, then you will be able to fill your profile. It looks like you spent a few minutes copying images and text from google. I recommend to make changes immediately before someone reports your account.
