Disable "unlike" for members

[Bob de Bouwer]

Hi there,

On the forum, members can hit the "like" button in a topic.
However, the can aslo "unlike" the topic again.
On my forum when you hit the "like" button, hidden content will open.
So i want to disable that people can "unlike".
Where do i do this per "usergroup"? I can't find it.

Thank you
Bob
