If such a volunteer becomes more confident after a while, they shouldn't hesitate to actually validate the task, if all was mapped well and they didn't have to add/change much.
When I look at finished tiles, I start with the intention to validate it. If I have to do too much work on it, I will sometimes simply unlock once again, either leaving a note it's actually complete now. If there is still more work than I have time for at that time, it's better to "invalidate", so another mapper knows where more work is needed.
