I'm asking this after seeing this question: Does anyone have the phone number for Rabbi Lionel Chiswell?
A Rabbi is a public figure, but still, a brand new user asked for his phone number and it was posted. What if the user intends to harass him? Maybe contact information should be limited to email addresses? The questioner could probably find a contact number elsewhere on the Web, but why make it easy for trolls and other undesirables? Would someone be allowed to answer a new user's question "What's DoubleAA's or Monica Cellio's or YeZ's or Gary's(or anyone else here's) phone number?" Those of us with reasons to can always put them in their Profiles.
I'm asking this because we seem to have a small number of hostile folks that don't like Jews occasionally putting up some pretty nasty stuff. Safety first!
Answers wouldn't be allowed for questions like "I'm an alarm system specialist. Can somebody please send me a link to the blueprints of Temple XXXX's security system?"...I hope.
