I submitted four reviews one day, and one was rejected with this message.
We value your contribution, and would like to be able to post it to our website. However, we are unable to publish your review because it violated the following guideline:
*Written with standard e-mail etiquette
The e-mail address associated with your account must be correct. We may need to contact you if there is a problem with your review, so make sure you have a current, valid e-mail address, please. No HTML tags. Please follow standard etiquette when writing your review. Do not use excessive typographic symbols, capitalization, or slang.
I don't understand what could have caused this. I did have a couple of parentheses, Capitalized only proper names, no slang, and I have no HTML tags in the review. I could post the review here if this does not violate guidelines. I took out anything I thought might trigger a filter and resubmitted it, but it is still pending after 24 hours.
