This can said as a trick or bug. I will explain trick by which you can create multiple Facebook account with single Gmail id. Well don’t be amused since this happens because bug in Gmail ignores the dot (.) in the email address. Well to make it clearer I will explain with the following example.

Consider an email id: alberteinstein@gmail.com

Now due this bug Gmail does not differentiate between mail ids with (.) dot for example

albert.einstein@gmail.com or a.lberteinstein@gmail.com

alberteinste.in@gmail.com

All the emails are same; well you can try it out yourself with any Gmail id, just try sending with such combination as above.

Well this same can be used to sign up Facebook, just use Gmail with different combinations with same id. When you use this trick you can sign up multiple Facebook accounts and your email remains same. 🙂

Hope it’s interesting, do comment.
