But isn’t it probable that after a certain length of time if the buyer still hasn’t filled in the requirements that they don’t want the order anymore? If the buyer no longer wants to proceed with the order wouldn’t it be best (most ethical) to give them their money back, in a reasonable amount of time (so they don’t lose interest on the money)? One downside being that they will lose the service charge ($2). But if they don’t respond to messages about the order for over a week or especially over a month/year they most likely don’t want the order any more. ie. even if it does affect stats (which it now says it doesn’t after a week), it still should be best to give the buyer their money back for a service if they no longer want to proceed with the order, and if it does affect stats it would be better to cancel a few at a time (low percentage of delivered orders) than have CS cancel them all at once after there are many which could give a very low completion ratio and a level drop.
Though I don’t think Fiverr used to keep the service charge. Ideally they wouldn’t but if the buyer doesn’t want the order they should get their money back, and not responding to messages for long enough should mean they most likely don’t want the order. Maybe it’s best to wait longer than a week to be sure (2 weeks or definitely no longer than a month I think) and if still no responses to request cancellation.
