It takes very little effort to associate anonymous profiles with identities. You can pretty much only accomplish this if you buy a laptop specifically for the purpose of having a FB identity and using connecting to the interent from a dedicated location not associated with you over tor. You need crazy opsec to really pull this off. The second any piece of info gets crossed, even things like ASIN's and MAC addresses, you are identified fully and entirely and that anonymous profile you made is no longer anonymous.

Empty accounts don't work. If "stealing identity" is the issue then you need to create a an active social presence and engage with the platform. A blank profile isn't going to stop anyone from stealing anything. That is weird advice.

Facebook will still associate data with that profile if you leave it blank. You probably have gigabytes of data associated with that blank profile on the backend.

If you don't have a profile then no problem Facebook creates "ghost" profiles out of the data it does have on unique identities. Remember an identity can be something like "this data is associated with this unique set of behavior" and does not always have to identify you with personal information alone.
