I would prefer not to restrict new users. I dont know how much of a problem this is for the mods but as a reader although I have seen some of these types of posts they are a big problem for me as a reader. They seem to get handled relatively quickly by the mods or called out by other readers.

So, as a reader I havent seen this type of activity get to the point that I would be willing to restrict new users to eliminate the problem. Now, I am not a mod so maybe they have a different point of view especially since they are the ones that have to deal with the issues when they pop up and since they are volunteers I would be more concerned about their time dealing with the issue than mine.

I dont think it is a bad idea just not sure if the activity level has reached a point to put this kind of thing in place.
