We sponsor transactions that don't involve any funds for every user over 1400 score. However there are some exceptions to this.
For example, sometimes gas might be very high and it wouldn't be sustainable for Ethos to sponsor every transaction during this time. We recommend waiting till gas goes down again so you can get sponsored transactions again.
Sometimes you still might want to proceed with the transaction. If you believe it's worth it you can always go ahead and do this.
Everyone gets a certain amount of allocated sponsored transactions every day. It's possible that you reach this limit with one transaction when gas is high or you only see it later in the day if you've been using the app a lot that day.
This also works the same way if you have your Ethos Everywhere wallet set up. You'll need to fund it to be able to use it while gas is high otherwise you will get a pop-up asking you to fund the wallet or skip it and use your normal wallet for this transaction.
To circle back to which transactions are sponsored, every transaction on Ethos Network besides Vouching/Unvouching and removing a review or comment is sponsored for users over 1400 score.
