Mods keep deleting

I keep posting about yesterday‘s episode and a sneak peek into their next episode on the trailer and mods keep deleting my posting. It doesn’t belong in this group when it does because it’s about real housewives of Salt Lake City. I don’t get it. It’s in relation to the trailer for next weeks episode which I’m really excited about. What am I doing wrong it says to posted it in BD why would I post it in BD when it’s not a BD episode it’s a Salt Lake City episode.

Any help?
