would you register a domain if

there were no searches for the exact domain but there was already another tld registered

for example myporn.net registered and myporn.com was free for the takes

Broadly speaking yes because you'll pick up traffic from the .net. I'll qualify that though and say it depends on the name and the site on the .net. If the net is a parking page, then it probably won't generate much traffic. Another clue is the length of time it's been registered. If the current owner renewed it, then he's getting some benefit.

its an active domain but im not sure about the renewel though
i also forgot the domain
but it crossed my mind as being a bit strange the .net being registered and not the .com

Well some people prefer .net, and some think it is better for certain sites - hosting and isps for example. It used to be the bloggers tld, but that has changed over the last couple of years I believe. It may be that the com was registered and has dropped, and the net owner doesn't know.

I saw that few times but net was usually parked and there was 0 on alexa so I didn't bother.
