In my case, you got it.
My mantra since 5th grade has been "None of your business"
At least in forums, most stick to the subject or a mod takes care of it.
Do you remember when Usenet was a discussion group? Some used to be fairly interesting in astronomy until the "Planet X" spammers got in the act.
Somewhere along the line someone will want personal info that you aren't interested in and don't want to give. Especially if it's not relevant to the discussion. Unfriend them, ban them, and there can be hell to pay.
BTW - almost every forum I belong to is under a different name.
