robots 작성 확인좀 부탁드릴게요~

특정붓만 긁어가게 하려 하는데 아래 방법이 맞는지 봐주세요..

User-agent: Yeti

User-agent: Googlebot 
Disallow:

User-Agent: Googlebot-Image
Disallow: /*.jpg$
Disallow: /*.gif$

User-agent: *
Disallow: /&act=dispBoardDelete/
Disallow: /&act=dispMemberSignUpForm/
Disallow: /&act=dispMemberFindAccount/

Disallow: /act=dispBoardWrite/

이렇게 작성하는게 올바른 방법인가요?
