I'm unsure about Unlike !!
Rate a member,
was on a personal level
Rate a topic was more on the level of Liking the content.
I'm against the negative buttons to be honest.
Take a look at this site, and scroll down for the "Kudos" buttons https://community.giffgaff.com/t5/Service-Updates/Found-an-unreported-service-issue/td-p/5862774
Its so positive and in your face, yours seems over bloated to what i'm used to seeing.
Yours would be a good break down page of what's going on.
The Kudos buttons are likes so to speak but members give much clearer and positive replies to get a kudos point.
That link is the best example ive come across of successfully using a positive like button.
Dont over engineer a simple "Like" please
