Throwaway domains from Namecheap

Has anyone had success in keeping any .88 cent domain alive on Facebook? I've tried warming them for days and as soon as I push too much they get banned. I've also tried .coms Same result. I'm cloaking everything with justcloakit.

I'm led to assume that Facebook is tracking domain age and any domain not a certain age isn't on their whitelist. Anyone know how to get new domains on their whitelist and avoid the blacklist? I've tried everything. Any tips are appreciated.
