I don’t think the user directory would show what users had liked your posts?
There is a ninja filter to group all likes or reactions received from a certain user if that’s of any interest? Eg
https://meta.discourse.org/my/notifications/likes-received?acting_username=USERNAME
On the reactions version you can include an extra bit as well:
https://meta.discourse.org/my/notifications/reactions-received?acting_username=USERNAME&include_likes=true
