Is that still up to date?
Fiverr's Payment Terms now say: "Seller hereby appoints Fiverr as Seller’s limited authorized payment collection agent solely for the purpose of accepting payments (via its Payment Services Provider, if applicable) from Buyer, and remitting those payments to Seller. Seller agrees that payment from Buyer to Fiverr shall be considered the same as a made directly to Seller."
This would mean that we actually do sell to the individuals on the platform, and not to Fiverr itself, no?
