At the request of the authors, the article titled “Spatial Crowdsourcing Quality Control Model Based on K-Anonymity Location Privacy Protection and ELM Spammer Detection” [1] has been retracted. The authors found in a recent experiment that a serious error was caused by the server hardware failure, so the paper was written based on incorrect data and there was a big deviation in the argument.
