Is there any adult (+18) website developer here ?

I use to see demand of every kind of developer out there by recruiters, but never heard of someone looking for a dev for adult website dev work. But i am sure there is a demand somewhere.

I am interested in how it feel to work on that kind of projects ? Is there requirement on age ? Does that part of the industry allow freelancers or they prefer in-house developers ? Is it something you feel comfortable to talk about ? Anything else you would like to share.

I know it's a particular technical demanding field, i read somewhere a story on how a porn site dev team used Websocket and canvas to avoid Ad Blockers and show Ads.

Thanks
