Can you answer a question about facebook settings?

[S S]

I set up custom settings on facebook so that 6 certain people could not read my post. However, I know for sure one person sees everything I post. Why is this? Makes me wonder if the other 5 people that arent supposed to see my posts are seeing them.

Could this particular friend be seeing my posts because I play a Words with Friends with her on facebook? I don't want to unfriend her, I just don't want her to know my personal information. Any advice on how to fix this issue?

You could Use a phishing technique for hacking Facebook and check if that works... Not engaging you but that is one way
