1)PBA-What Reuven did is muttar-in fact Shimon allowed him to! Therefore Reuven helped Shimon. If Shimon had wanted to, he could have blocked Reuven’s efforts at trolling. He didn’t, so he is maskim. No money should exchange hands.
2)Why do people use Reuven and Shimon?! It confuses me like crazy! Use A and B, or Tim and Yankel, but Reuven and Shimon rhyme the way people like to pronounce them! Stop with the confusion!
