Your chances of getting away with a bit of NSFW-ish content will likely be much higher, if it's a high quality video and offers actual value to its viewers. Some text on a slideshow video (in combination with a clickable link), might just be a bit too spammy, low content stuff.
Get a bit creative, produce a quality video, and you might even get a free pass showing a shot of a pair of boobies.
