Correct me if I am wrong but I belive that was an abuse of power by the moderator based solely upon his or her individual opinion.
That comment shows a fundamental misunderstanding of this site and I am delighted to correct you, Helicopspeeder, because you are entirely wrong. Pprune is a private site, paid for and maintained by Danny and others, and neither you nor I nor anyone else have any 'rights' whatever. If Danny or a moderator decides (based solely on his or their individual opinion) that they don't like a post, or series of posts, they are perfectly within their rights to lock, delete or otherwise censor without being required to justify their actions. If you don't like it - post somewhere else.
