The Phalanx extension is available only to staff members and those part of the VSTF. If you're having issues with spam on your wiki, use the VSTF's report form.

You're chances are pretty much zero of having access to this extension, even through Special:Contact. As Tupka stated, global tools are not given to regular users just because you asked for them.
