I am at the mercy of the buyer for an entire 30 days as long as they have that power to review over my head. I have some very distraught demanding buyers who use that to force me into long winded chat sessions that whole time. While I am always happy to answer questions, some buyers take advantage of me and I have no choice but to answer and respond to endless messages on a daily basis.
If the time was only a week that they could leave a review I wouldn’t be constantly feeling blackmailed for 30 days and at the mercy of some thoughtless buyers.
Some other buyers deliberately use that to force me to chat with them for that entire time. Yes, there are some who relish that control they have and use it to the max.
