Certainly there's something to say for both options. Those who don't cooperate with such publications can be perceived as more discreet and mysterious (in a good way). On the other hand, publications may bring marketing value and lower the stigma which I understand may benefit the escorts who mostly deal with that.
It's never wise to copy, especially not from direct competitors. In my opinion it makes you look unprofessional and quit frankly, rather stupid. In addition it can negatively influence your search engine ranking. I have browsed plenty of escort websites and it's easy to tell whose content is original and who copies. I don't want to point the finger to those who are copying but TCC, Upclass, SS, Secret Agents, Khloe all appear to have original content that they wrote themselves.
Last but not least; have a great weekend everybody! Any exciting plans (with an escort)?
