do you have any proof? You cant just post publicly "X is a scammer" without giving proof. If you do have proof I also recommend posting this to the Service Review section of toyhou.se instead of here
LowLightFelix is a repeat scammer looking to steal adopts and sell them for cheap. They've done this to several people and even I have been a victim as someone who purchased one of "their" adopts. Please be cautious if you intend to purchase anything from them.
And if you sell adopts, you may want to check their page.
