So, it was neither a cyberspace SNAFU, nor a "religious" censorship. Next time I should really read the directions.
Here's music-discussion.com's response
"Hi The thread was deleted as it cantained a link. We do not allow first time posters to promote links, as we are trying to promote a community atmosphere. Plus if we allowed all the members to post links, then we would have hundreds of posts everyday of members coming here to promote other sites, meaning the quality of the Music Discussion is comprised.
However, as you have contacted us regarding your post, I have undeleted your thread but removed the link to comply with the forum policy.
All the best,
