Did you tell support in your ticket that it was a ‘technical error’, as one of the reasons mentioned in your screenshot?
From my point of view, a buyer clicking too fast, having big fingertips and a small phone screen, etc., should count as a technical error.
If such things would count, I wouldn’t find the removal of the option too bad, as the reasons they give are really the only valid reasons I can see to request feedback revision.
Actually, if the bad feedback resulted from a technical error, abusive buyer behaviour or is a TOS violation as stated in the screenshot as valid reasons to ask support for removal, then at least in the latter 2 cases, I’d rather ask support to deal with it than requesting removal from the buyer.
And the “technical error” cases, well, support should know of those, so the errors can be fixed, respectively, like in your case, the tech team should work on a solution that avoids that kind of technical error from buyer side, like showing them an overview of their review and having them actively check a box for “yes, this is the review I want to leave” and a back button if they realize they clicked too fast or the phone did only register 4 stars where they wanted to click 5 or whatever.
So, all in all, I don’t find it too bad, however, cases like yours should be covered.
Generally, I’m for “text only, no stars” reviews, that would nix the whole issue, but that’s a different discussion and since everyone does stars, chances that they’d want to dare swimming against the current and be different are probably low.
