In my experience, Synthesia.io takes a serious and professional approach to the platform's integrity.

This can cause short delays if a particular piece of content must be manually reviewed by staff before being released.

It can sometimes be annoying if you are in a different time zone, so prepare your materials beforehand and don't wait until the last minute.

Despite this inconvenience, the staff is super friendly, understanding and eager to help, so I've been using this platform since their startup days. Review collected by and hosted on G2.com.
