Try an experiment, then. Create a new account and submit the extension under a new name unrelated to facebook. Grow your userbase to a size significant enough that FB notices. I am betting that FB will get it taken down again. Trademark Infringement was just the scapegoat for your original extension. The real reason it was taken down was because it was harming FB's business model for a growing portion of its userbase.
