Kane's sig was 540 x 120 and under 50 KB, safely under the sig limits. If you want to make a rule stating you can only have X number of images in your sig, go right ahead, but make it a RULE. You shouldn't just ban someone from using sigs because they broke some secret rule. Make it a rule now, go ahead, it's a good one. But it wasn't a rule THEN, and he shouldn't be punished under some ex post facto ruling.
