The problem with the NSFW community on Steemit is the number of plagiarists and spammers. There may be a few prudes who flag properly-tagged NSFW content, but your verification post link should be adequate evidence you're not a fake account. Embedding your verification image and a link to your original intro post at the end of your new posts should be more than adequate. Just save the text in a file on your desktop for easy copy/pasting.

Oh, and be sure to use the NSFW tag first on any NSFW content just to be on the safe side.
