Yeah. Sly, little tricksters they are. They comment on really awesome art pieces, such as yours, & people who visit the art thingy get curious at all the other artists & click on their username. Henceforth, getting publicity.
I actually do click on their name though. That's how I found you. Yeah, either that, or you sent me a Llama, or you added something to your favorites... That's how I usually come across people.
