What effect does pointing multiple domains to one of your sites have?
 

Will pointing a number of domains at a single site, have any effect upon its SERPs?

I'm thinking more in terms of the danger of it having a negative effect.

I have a few fairly premium names that I'd rather point to a related site than try to build pages/sites for each. They might get occasional type-in traffic.

You could just create a lander like Xvideos does. Simple, probably more effective and less negative impact.
