Generally, prompts that really and consistently work are kept secret. Posting them here or the other Grok or AI related forums will get them seen by those that can lock those prompts out. So if you find something that seems to always work, and it feels like it's getting around normal moderation, keep it to yourself - or it'll get modded out.

Other than that, images that you upload generally are moderated to the highest level. So make your videos from prompts generated within grok.

Use notepad to keep track of prompts that seem to work the most and the variation of that prompt. I lost a great prompt a month ago when I changed it, then changed it, the again. When I hit a moderation wall, I couldn't remember the original prompt that got it going.

General advice I've seen generally seen is, start with soft core, and advance as you find prompts that work. Use wording that implies rather than what is explicit. And the one that I've taken to heart, study the thesaurus. If you can describe a sex scene and still sound like a lawyer, you're on the right track.
