I have often felt that many scenarios make it so that you are identified by following them. And, if you report on something strange that happened, they know who you are. I am banned from a local restaurant for two years. I completed a shop with my husband and the waiter was terrible. I reported it. The next week they were still begging for people so I had my sister sign up. I went with her as her guest and she got a 10 on her report. The next time she tried to apply, they denied her. She kept applying for others and getting denied. Finally she called them on it and they said, "You and the lady you were with have been identified as shoppers and are not allowed to shop any more." I think it's pretty crappy that I got identified on HER shop. They still beg for people every month and sometimes even call me or text me. When I say, "ok" she writes back, "Oh, sorry. Can't assign to you." Had we not pestered them, I would not have known I was outed. My job board just says, "not available" when I try to sign up.
