To prohibit someone from ever returning to something or some place. My rude comments got me banned from that website. My friends and I were banned from that restaurant after we started a food fight there.
ban someone from something
1. to prohibit someone from doing something. We banned everyone from smoking. Everyone has been banned from smoking.
2. to prohibit someone from entering something or some place. (The same as bar someone from some place.) They banned us from the building. The manager banned the children from the theater.
