Did the Answerbag member "Gtravels" ever join Answermug?

The reason I ask is because I've heard from very reliable sources that she has been seen on a site called Similar Worlds, of which I am a member. The mystery is that Gtravels has blocked me on that site even though I use a different name there and I haven't interacted with her on that site yet. How would she know who I was? Or did she mistake me for someone else?
