My comment not showing up?

Made a comment in one of your stories 12 hours ago, it's not showing up, comments after I made mine are.

Noticed a "pending approval" message when I submitted. I wrote nothing offensive, just opinionated. Is my opinion not favored and shown unless it falls into the bias of those that approve it? What kind of system is this?

If you use certain words, the comment gets hidden until a mod approves it. It has nothing to do with your opinion..

That's strange, because I didn't use any words against the ToU nor anything that could be seen as really offensive.

after refresh page everything in comment go void or nothing just gone!?
