I’ve got scam buyer

Hi everyone,

 

I need your help. When I post my items the scammers click buy it now, and haven’t paid yet. Couple days later eBay removed my list. Because of this buyer authorized using account. I report it and blocked, but he/she’s still using different account to click buy it now. I have this problem again and again. When I looked at the message that he/she wrote on it showing the same what’s app number and message contents. So I recognize that he/she is the same person as eBay removed it before. It’s lost my time for advertising for real buyer because just these people want to get my stuff for free. I have to input information manually again and again over a week. Could you please give me the advice If someone click buy it now. What should I do? Could I ignore it but I have two days to respond also if I’m not excepting what will effect on my credit? If I cancel order but it doesn’t have an option to match with this situation. 
Could you please help me for this situation?

Thank you
