You can hide them by using the following CSS in your wiki's MediaWiki:Common.css page:

Note however that hiding "This reply has been removed" will mean that it's more difficult for everyone to see where a reply has been removed in a thread.

This may confuse people if they re-read a thread at a later date and some replies have "magically disappeared" -- whereas if you leave the "This reply has been removed" there, at least they can tell that the reply was deleted.

Personally, I would leave "This reply has been removed" in place. I don't really see it as spam, actually I think it helps keep the flow of the conversation intact.
