This has happened to me a few times. Like, once or maybe twice with Thyme...but many times with Maxwell, mainly from mate beggars...
Here is Thyme:
Simple design yes but the underfur is hard to get right, as well as the eyes. And I really only remember one time. And that as in Sky's Rim, years ago, me and my friends were chatting and one of them poofed then came back looking nearly the same as Thyme, just for fun. I was okay with that but then she kept getting closer and closer to the design and I think she started to copy my bio. I asked her nicely to please stop but she kept saying it was just a joke, eventually my other friends ganged up on her before she stopped and it was kinda awkward when she came back but then we went back to talking.
Here is Maxwell:
Again, a fairly simply design but my God....I spend a lot of time with him at Bonfire, right? Home of the Mate Beggars. Well I specifically remember two kinda of incidences were people have copied him. Once was someone named snow. He had the same colors, I think nearly the same size, but he had a forward Mohawk. Now that didn't bother me so much...but...he walked everywhere. Maxwell ONLY walks everywhere. And he kept sitting RIGHT next to me and staring for a minute before looking away. Idk if he was trying to get my nerve of what but I didn't do anything. The other was yesterday. I was watching the Mate Center and this chick comes over to me, same style and nearly the same colors and lays down right next to me. I tell her no before she even says anything and then gives me the excuse that her pelt changes color when she gets nervous...So...Idk...
That was a off topic ramble I feel o.o....whoops...
But anyways, copying/stealing chars doesn't bother me TOO badly because usually I can chat with them and then they usually end up admitting they wanted to look like me, so it's all good lol
