Haven't visited this issue in quite a while but I wanted to post some updates.
The situation we talked about -- providing contact information inside a deliverable -- has turned into a real problem for Fiverr. If a buyer complains, they'll ban the seller's account.
What's worse are the "smart" people who offer an ebook or such, then require the buyer to go to a login page to get it, thus collecting their email address. Again, sellers are being banned for this.
Once banned, you have to wait at least 45 days to collect whatever money is in your account. The wait is that long to account for potential chargebacks.
