Install the Redirection plugin and set up a redirect.
Simplest way is to set up a redirect for every url i.e.
Source url -> yourdomain.com/category/?filter=latest
Target url -> impregnationporn.com/category/latest
Of course that could be a fair bit of work depending on how categories etc you have.
The plugin allows for wild card and string substitutions so with some experimentation you could probably set up a single redirect to cover everything: redirection.me/support/redirect-regular-expressions/
