Ok, let me pornsplain. What Shyla allegedly did was dishonest and wrong- the getting paid up front by a studio then not showing up.

As for other porn girls, maybe they don't make a big announcement just in case they'd like to come back again. Personally, I didn't make a retirement announcement because it's not like I was some executive resigning at a Fortune 500 company. It's just porn! I think announcing retirement is only warranted if you're extremely porn legendary like Belladonna or Jenna Haze.
