Re: Like many of you, I work in IT
But, the PROBLEM is is that this sets up a dangerous precedent.
Once the floodgates open, there's going to be too much momentum to reverse the damage. Once a company with no legitimate need to ask it even as a "test question" succeeds, others will attempt it. Eventually, it'll be so common that people will have had it inculcated in them and plenty will not be savvy enough to have an "alternate" account.
Besides, officially (well, last time I read the Ts&Cs), facebook prohibits an individual from registering multiple accounts. Not that people don't, and not that fb cannot handily do proper counts to not inflate redundant, hijack-recoveree, or business/personal accounts.....
