I had an entire fake profile so that any data entry would match if I reused it, but it wasn't traceable to me. I even had fake fb accounts, but that was more so that I could see mine as a stranger would and double check privacy settings.
Now I just close it.
I wonder if anyone reads the logs.
Also I wonder is anyone ever reads firstname.lastname@example.org since it must get heaps of cool hatemail and spam.
