HTC Sense and Facebook

[AC Question]

I got the HTC One (M8) yesterday and HTC Sense wants to sync with Facebook. I allowed this action, then a pop up appeared asking if I would allow Sense to post on my friends walls. I have denied this action but it keeps recurring. If I was to accept this action, what would be posted? Would it be something that would be run past myself first to check or not?
If somebody could please help me with this I would be very grateful.

I think it just needs your permission so that if you use the HTC Sense Facebook interface to post on a friend's wall, it will have the proper access. I don't think it's going to be posting stuff without your knowledge.
