Some odd things in their guidelines
"Videos must not include profanity, nudity, obscenity, pornography, depictions of drugs, alcohol, tobacco, or any harmful or illegal activity.
Data has said "shit" in startrek before.
There has been some nudity in a couple of episodes, bum shots.
The entire crew of the enterprise got intoxicated on drugs in more than one occasion.
Some startrek drinks contain alcohol.
I'm sure there have been characters on the holodeck smoking tobacco before.
And.. if you can't show any "harmful or illegal activity" then anyone being murdered is out. No spaceships blowing up and killing anyone, unless it was accidental.
"uniforms, accessories, toys and props must be official merchandise and not bootleg items or imitations of such commercially available products"
This also seems a bit problematic, official merch/toys is often inferior to fan made props
