First off not trying to start an argument here. If that were the goal the prior comment would not have been so subtle. You certainly did not offend me or cause disrespect to anyone that I know of.
Now to the point: this forum has for many years been a resource primarily for cast boolits and as well for all sorts of other things mostly shooting related. The reason it is a resource is because all sorts of information from how to properly fit a cast boolit to a throat to perhaps making venison jerky is shared freely. There are literally thousands of threads containing tricks, tips, hacks, etc.
Note the sub-forum title: Projects that you have made, have done, or are doing. The things that you have poured your heart into and that may help or be of interest to others.
It has been acknowledged that you are a craftsman and as such you are entitled to keep trade secrets. I must admit I keep trade secrets in connection with my business however when on this site comments, advice, etc are contributed freely. Now I suppose if this thread existed within the vendor/sponsor section of the forum there might be some justification for it as a teaser to entice forum members to do business with you. Aside from that what is its' purpose? All the other threads in this sub forum either detail a "special project" along with an offer to help replicate or they are an appeal for help to which help is freely offered (if anyone has the needed knowledge).
So it is not a matter of having done something terrible. It may be as simple as such a thread not belonging. Of course you are free to disagree respectfully as a free interchange of ideas and thoughts is often healthful.
