For the sake of fairness I'll not tell you why Mr Kohl was banned but can assure you it was not for a lack of knowledge. It had to do with personalities and was not an easy decision to come to.
I'll agree there is a dearth of studies that demonstrate the effectives of pheromones but there have been a few that were pretty well documented and conducted. While not really valid for scientific purposes there is a lot of empirical evidence that they do have some effect. Being a huge sceptic myself it took me months to convince myself that the effects I saw were real and not my imaginiation. Of course the results were purely subjective and actually focused more on business results than anything else so may not even be valid for you from an empirical point of view.
Look at the settings on the forum. Most likely you have it set to one month. Go to the forum in question and scroll down to the settings. Change the time from 'one month' to 'begining'. If that doesn't work for you let me know and I'll see what I can do.
