Amazon has done some changes

Hi friends , i want to know has amazon done some kind of changes because review is not publishing and i am asking for usa if any other guy facing same problem so plz discuss here so we can help each others. Thanks

How long has it been since the review was posted? Sometimes I've seen them take a few days to show publicly.

Also, sometimes they remove them depending on various filters and/or manual actions if they don't think it was a real review or it broke a rule.

problem happened from yesterday

"problem happened"

Does that mean the review was submitted yesterday and hasn't shown up yet? As I said before, I have seen it take at least a few days (and edits even longer).

If you meant something else, you should try being more specific of what action has been taken, what results you expected, and what results happened or didn't happen.

Also... this doesn't really seem like a topic for "Blackhat SEO"?
