We've noticed people lamenting the disappearance of certain posts and to avoid misinformation and bizarre conspiracy theories, this is how it is:

If a topic starts to attract negative posts (reported to us or otherwise), we will do our best to remove the posts in question rather than kill the entire topic but if things get out of hand, we will either lock the topic or simply remove the thread if it is relatively new and has not had a huge response.

The original poster is welcome to restart the topic if they so wish but may want to include a note to encourage posters to stick to the topic or play nice.
