That language means you can’t make actual porn with it. I’ve worked on a show where we used stock images for fake girlie magazine covers. Have your legal department look over the TOS and sign off on you using them

For street photography a good technique is zone focusing. For example F8 on a 35mm you can pre-set your focus to 8 ft which means that everything from about 5-1/2ft to 15ft away will be in focus. No waiting for your auto-focus to catch the subject, as long as they are withing the zone, it will be in focus.

Here is a site that explains this technique in better detail
