Could you clarify which thread you mean? Do you have the title?
Our team does not delete threads. In some cases we move them to the appropriate categories.
Until a few months ago, a person who started a forum thread could delete that entire thread, including all posts of those who responded. For that reason we have disabled this ability now, but we can't bring back what got deleted before.
