1) is sell porn ( gifts , tokens m videos ) allowed here ?
Yes, probably. Sell things on the Services or Goods boards.
2) can sell some html codes for some porn site ?
Yes, as long as you're not stealing the code from someone else.
3) can share my old works url that contain porn (as proof and to design like it ) ?
Yes, as long as you own the URL site and code. If it's just example of your work, you don't have to own it. You should find a way to prove that the work was done by you.
4) need to add some words for topic subject ?
What? This literally doesn't make sense.
Just my thoughts.
