Keno Ogbo was speaking after Facebook CEO and founder Mark Zuckerberg said the company is planning to introduce a 'dislike' button to accompany it's 'like' button.
Mr Zuckerberg said Facebook had been inundated with requests for a dislike button, and that it could be used to show empathy and sympathy with others, for example when a loved one dies.
However critics have said Facebook users would use the dislike button to bully other people.
Keno Ogbo told Premier's News Hour: "YouTube has had a like and a dislike [button], but it's not personal. It's not an attack. I think Facebook really has to be very, very careful.
"I may disagree, but to dislike is not a good idea, it's not something I think Facebook should go with...quite serious things are happening in the world today, we don't need Facebook getting another non-issue and making it a news item.
"The reality is that a young girl, maybe about 14 or 15, might just post a picture on Facebook or might just post a comment on Facebook, and you have some very vindictive people using the dislike button.
"I really don't think people are going to use it in that sympathetic way."
