Drunk block doesnt work

I got this app specifically for the function that would supposedly block me from calling or texting designated contacts while drunk. I selected the contacts I wanted to block and enabled the block. But all it does is wipe the names off of the contact. The contact is still there and still accessible. I had texts from one on my phone, and it only displayed the number but I could still tell who it was because of the texts. Plus with iPhone, I know you can type an old contact name into a message and even if the number has been deleted, the phone remembers and will suggest it. I didnt try this but I bet it would still work that way. Disappointing app. Plus absolutely no one I know is on it so it made every other function obsolete, including hot spots, which I thought would still work just with other users in the area, even if they werent on my friends list. I deleted the app this morning and will not be re-downloading.
