Loops ... my recent flounce is wearing off slightly. You will calm down and feel less angry about this. But when you do come back, I really don't think it is a good idea to report iffy posts if they aren't directed towards you. It does make you (one) come across as a bit prefect-ish, or even the infamous professionally offended, and that is very much disliked on Mumsnet as a general rule.
Someone reported a.n.other poster for being horrendously rude to me once and the post got deleted, but I was really furious. Had I wanted it deleted I would have reported it myself.
This is not to say that your motivations weren't sound, but you know we mainly are big girls on this site.
