Forum Software with “Posts hold for moderation”

Hello guys,
im looking for a possibilty to make my comments look nicer and be more comfortable. So i was looking at rs-discuss, XDForum, Vanilla, SMF and more.
Actually i dont want much of the forum software, but 1 thing i dont want to miss is a blacklist which holds the comments for moderation.

Since it doesnt show that feature on the page and i dont want to install every1 of those forums i was wondering if any1 can help me with the question.

Btw any knows if there is a nice comment-rating plugin like engadget is using it?

Thanks in advance
