The idea of having to explain how I vote, explain my opinion, bothers me a lot. Voting is subjective. I don't think anyone should have to explain why they vote, be it for the presidential candidate of their choice or their opinion on a sex toy review.
It's nice when people ask questions so you know what they didn't get from your review but I don't think it should be required.
Then again, after so many years, I rarely worry about down votes. A few just don't matter and a lot of customers, who don't participate in the forum or the review program, don't necessarily understand they're voting for the review, not the product.
It is what it is, I guess. I remember the days when you could vote multiple times and it didn't show who voted."Haters" would vote not useful at all on reviews every day just to drag your rating down.
A few less than perfect votes now seems mild in comparison.
Course, I'm just an opinionated old lady so feel free to ignore me
