Private Commissions

[taasla.livejournal.com]

Hi artists_beware!

I'm coming in to ask how you some of you guys handle private commissions. Do you charge anything to keep a commission private?

I've been approached to keep a commission private, and I agreed to it because nothing in my TOS covers that. I'm a little bummed because full color pieces always tend to bring in a good number of potential customers. I'd like to add a clause in my TOS for private commissions for the future, but I don't know what to do with them, or what an acceptable fee for keeping a commission private is. (If charging one is acceptable at all.)

Edit: To be more clear, the person in question does not want me to post it to my gallery when I am done. I am not handing over my rights to them.
