As we can see for example here, a considerable part of the non-professional, or non-sysadmins are coming here only because they don't know, where is the exact place of their questions. They don't have any negative intentions, only don't know the system enough well.

At my very beginning SE experiences I also thought many times that serverfault is only a redesigned clone or stackoverflow, for example. The sites look very similarly.

My suggestion were to improve mechanisms to help them to find their way to the correct site.

I also suggest to vote for migrate them. If 4 from 5 VtC voters are vote equally, the migrations would be executed, without a moderator must take the weight of its responsibility.
