When I post something as a responce to something and it gets deleted, I have a right to know just what exactly went on in there.
Exactly what causes you to believe you have that right?
I am blaming Nils, the corrupt and omnipotent dictator who chooses to obliterate posts at will. How are we certain that he doesn't just delete other posts too, even those of good quality and informative nature?
You can of course not be certain but here are some reasons that I hope can help you getting less worried:
1. Only one member (or at least very few) out of 13039 has taken up this issue as a problem.
2. Only about 1% of the total posts are being deleted. 95% of those deleted posts are spam, copyright law breaks or replies to such posts which consequently become useless.
3. The policy is to inform the poster about deleted posts but this is not always followed in case of spam, trolling or repeated breaking of the forum rules.
4. If you look at this website and forum objectively and consider the reasons for why it existist, do you really believe that posts of "good quality and informative nature" are removed without good reasons?
With this said I must also admit that I am just a simple human beeing which occasionally make mistakes or not so well judged decisions. Sometimes the aim to quickly take care of issues to keep the forum clean, "family friendly" and to avoid discussions taking off in dangerous directions are of higher priority than always informing everyone about everything. I am afraid you have to accept this if chosing to utilzing this website.
However, in doubtful cases I am always open for discussion.
You do apparently have a very negative view about how this forum is administrated but I do not really understand what your real problem is.
Please understand that I am not your enemy, just dedicated to making this website as useful as possible for people interested in classical piano playing.
