Submissive could mean a lot of different things.  Does she just want the guy to take the lead?  Does she want to be tied up?  Punished?  Humilated?  Maybe she could recite a short (but non-explicit) scenario.

Lester is spot on, and to protect herself, she needs to establish clarity in her initial communications.  I have dated three declared "subs" off of SA.  Two of them just didn't want to think in bed -- wanted me to take the lead.  The other one wanted to be led around on a leash, lick my shoes, be spanked with a ping pong paddle and gagged for several minutes in a row.  So your friend should probably not let any potential SDs be confused on what she wants.

To put a slightly finer point on this, she might want to carefully consider how she words this in her profile.  

 
Context is important.  There's a difference between saying "I tend to be submissive during intimacy" and "I want a Daddy to Dominate this Sub."  

 
And I suggest you give her some guidance on not adding anything that can be, even loosely, interpreted as P4P.

Thanks for the suggestions. I realized I could filter for that on SA.  I could see how other women phrased it.

I met one woman who had a very scary experience with BDSM; she actually though he might kill her and dump her nude body in a ditch. In the end she wasn't physically harmed very much but it was a scary experience that still affected her a couple of years later and put her off bondage for life. Another sub wasn't so much a sub with me, just very open minded and enthusiastic about what went on BCD so long as it didn't involve pain or injury. Since sub-/dom- never did much for me, this was just fine. I only found that she considered herself a sub through pillow talk.  

Your friend needs to communicate her interests and limits in her profile and at a first meeting before going BCD. A safe word probably isn't a bad idea if she is allowing more than just being passive.
