Yes. The reviewer can simply not enter text into the "written review" field. The review used to default to "." but I have recently noticed that in some cases no characters are written at all.
It would appear awkward to reply to a nothing, empty guest reply, followed by poor star ratings.
In terms of reply to guest, rantings and ravings might be fine for some hosts, but not me LOL!
I believe Airbnb has clearly defined reasons to remove guest/host posts. I don't think blank text or sparse words such as "not clean" , followed by stars process, would qualify.
@Harold75 You’d be out of luck getting ‘not clean’ removed, but I would say use the ‘not relevant’ angle to get a blank review removed, and hope any stars go with it. Worth a shot maybe. That’s if you’re motivated and able to stomach a go round with Airbnb CS.
@Colleen253 Yes! Getting "not clean" and the stars that go with it, would surely be an uphill struggle. Good point on contacting Airbnb CS about * not relevant,* but like you said, it's a long shot. Understood! I don't have enough lifetimes for that go around.
