Once I decide to be anonymous on a website it is self-defeating for me to try to identify myself in other ways. Although, it's useful to know the country at times, because in some forums posters sometimes talk locally and one doesn't know what they are talking about. Especially political comments where meanings can depend on the country of perspective.
None of my neighbors except one know I have pinball machines in the house and I like it that way. I don't need them to brag for me. My machines are immobile and make my house a sitting duck for crime. They're not like jewelry where I can stash them out of sight or off-site.
It's not enough to tell myself that a thief won't be able to walk out my door with a pinball machine. He may not realize that until after he breaks in. After all, my coworkers think a slot machine is a pachinko machine is a pinball machine is a gumball machine. No telling what a burglar thinks I have once he gets wind I have mucho coin-op. A burglar who thinks I have machines too huge to steal might break in anyway, thinking I keep money in them. Then he breaks the coin doors, because I didn't leave the key in them along with a note that there is milk and cookies in the fridge, then he finds out there is no money in them, then decides to smash the backglasses for satisfaction. Then he tells his peers where I live. Then I'm on the local news telling others what lesson they can learn from my experience, with the smart ones shaking their heads that I wasn't already careful.
Better to keep it on a need-to-know basis. No one needs to know unless I vet them first.
