They're (obviously) fake numbers that direct you to scammers.

That probably won't work, they use proxies. We had a similar problem  
on our wiki. The only way I managed to stop it was by adding a regex  
that blocks all added text that looks like a toll-free US phone number  
(with support for filtering out some obfuscation). It has some false  
positives from time to time, but it's the only way I've found to  
contain the problem.
