I've had someone PM me from a toon with a name that *looked* the same as a clannie's and try to fast-talk their way into getting me to loan my camo "to help them lix". The two reasons this didn't work:
1. I never loan lux
2. The toon being impersonated was actually *my* alt
With that said, I did once lose 42k to someone posing as an alt of a well-known, honest player saying they were selling bloodlust. I gave gold to the "alt" who said they would trade helmet from main but "something came up irl", so they would get me later. When I asked the main later when I could get helmet, they said they didn't have an alt by that name
