Facebook Comment in Top

Hey guys.
Do you know any way to rank comment on top in Facebook fanpage posts?
Few months ago I tried facebook auto likers and it was working.
But now most auto likers are dead beacause facebook make changes in app permission.
Pleas suggest something if you have knowledge.
Thanks!

few months back, some smm panels were selling this service. Don't know if it is working right now but you can try to find these smmpanels who are still providing this service.
