Can anyone explain this to me

On this site I noticed this message Avoid scamsSigns of fraud wire transfer money orders cashier checks payment via gift cards shipping escrow transaction protection guarantee . Be safe by dealing locally. Can anyone explain to me how a cashiers check is a type of fraud when its a guaranteed check issued by the bank in which you cannot order unless you have the proper amount of money in said account My Capital One Checking account has this feature where I can order a Cashiers check made out to whomever I choose but a long with a fee I also need the exact amount of money available in my account in order to order it in which it delivers in one business day to the address I state for it to be sent to. That way there the bank can guarentee that the amount on the check is valid and the check is confirmed and able to be cashed with money immediately deposited for use. So why is it listed as a type of fraud And also I never once had this option before I opened this account a week ago so is it something that I should use for housing payments Please comment below.
