On the other hand I don't think the example screenshot from @LC18 conveys the same. (I am not a French speaker, so maybe things got lost in translation) For me it was an upset customer venting about a bait and switch. Yes, he does call her ugly, but considering the context, I can understand why those words were chosen.
He called her fat, ugly and used a word in French that could be translated to “fuck” but even more vulgar. “Fourré” as opposed to “baisé”.
Like I said in another reply, I’m not telling people they cannot be angry and write truthful/honest reviews. That’s the whole point of having a review board. They should however express themselves with a little more manners.
“She came in, I paid her, I fucked her 5 minutes, I emptied that.”
is exactly the reason women don’t like reviews and don’t want to join merb. This particular review was discussed in private conversations.
