Putting my hat on the ring
Some arguments:
1. We were all first time posters at some point in time, some of us just were lucky enough to post for the first time when the posting police was not in place and migth have gotten away with exactly what we (all) are now, so diligently policing the board for.
2. Grandfathering: The act by which if you have been on this booard since before Mathusalem (in this case the magic number seems to be between 1 and 1/2 years 3 and 1/2 years) you are automatically not only the owner of God's truths but also capable of decerning Good from Bad and bestold credibility or decern evil onto someone else's contribution migth not be the best way to promote particaption on this board. There are, still, way more people looking at this than there are contributing to it.
3. I do not see the need to start with a bad review of someone to gain credibility on this board, if you do not have any usefull information concerning the provider for all of us, and the only thing you want to do is complain then go back to your Mom!
Usefull information about a bad service (did not got what was promissed, did not got the girl that was offered, her service was not to par with the offer, etc) are all examples of good information that we can all benefit for.
4. Bogus contributions can also come in the form of a bad review, from people trying to get even for something, other providers, other agencies or friends of other agencies, so the fact that the review is bad does not automatically makes it credible.
Now you can fire at will
