I only talk about things that I'm knowledgeable about so I make sure I don't say anything inaccurate, in aspects that I'm not well versed I read, take notes and make research.
And I haven't had an issue with a deleted post, it was just moved
Then I think you should drop the link to the post let's see for ourselves if the moderators were right to move it because most times when people complain about a moved post, the moderator ends up being right about moving the post.
I have seen a post or two that shouldn't have been moved, but most of the time, it was the right thing to do.
