Yes, but I've had instances when it has been blocked when the seller and I have had extensive communication between us re item, postage etc and I'd have liked to have given the seller 5 stars for really good service. As I said - it's not consistent!  😮

Maybe it does not count if the communication is before you bid?  But as Dave said; if you could not leave stars, your seller did get the automatic 5 stars  🙂
