I disagree with your comment below in principle. Requiring regular users to modify their behavior because of the actions of a few bad actors just ruins and complicates the experience you are trying to create. Dealing with spammers comes with the territory and is my responsibility, not my visitors.

How many of us would object to giving Wikipedia our mobile phone numbers in order to help prevent spam? or WIkia? It is all about interest and passion. I am sure that even the furries who edit Wikifur would be happy to give up their a mobile phone number inorder to edit pages.
