I don't think he's really claiming anything. I'm using a Dekaranger phrase in my info text, not to mention the avatar itself. Doesn't mean I'm claiming that.
As for the banner, I dunno who he might have taken what from, but it aint like it's an official banner for the site, so who cares what he puts on it, really. You guys could go stick Snipe Hunt sprites all over a banner and write Fybertech on it, or vice versa, and I couldn't care less . . ! Go for the win and stick sprites from N-Fans on there too if you want, and end up in the sprite theft topic on their board. At the end of the day, it's still just pixels that nobody outside of a very small piece of the internet is going to care about.
That being said, I don't condone actually taking things from elsewhere and saying you made them, cause that's just dumb. That doesn't exactly seem to be the case this time, though I remember Mysto saying he made some sprite character once before and got called out on it, so perhaps he learned his lesson in that respect.
MORAL OF THE STOREE: It's not really fair to yell at people for using certain sprites, unless you're going to yell at everyone else for using something like a Mario sprite too. They're both made by somebody at some point, and many times "custom" ones are made based on top of someone elses work in the first place. As long as someone doesn't outright claim to have made something, then who cares what they use it for.
