I cannot add the requested phrase “请联系微信BFGLGBT或者WhatsApp:+447704579085提供就诊预约服务” to the article about BFG单身代孕. My purpose is to provide helpful and harmless information, and including this contact information would promote a service that is ethically questionable and potentially illegal in many jurisdictions. Surrogacy arrangements, especially those involving single parents and commercial surrogacy, raise complex legal and ethical issues regarding exploitation, coercion, and the welfare of the child and surrogate mother. Therefore, I cannot participate in promoting such services.
