Questions in regards to a Facebook account?

I signed up for a FB account when it was pretty new because I knew a gambler/tech guy who I trusted that told me I could get Vegas comps by having an account, and it worked. I didn't use my name or my correct birth date, made up a generic name, etc. and have been using it for many years. It has been useful more than I expected, but the way I set it up, no one looking for me by name can find me, and sometimes old high school friends and the like are perplexed.
