^ Technically speaking Vod is correct, vphasitha01 cannot reach 100% accuracy because...wait for it...he is banned.
If vod mean that user already banned and that's why that is impossible then Vod is right. But I think Vod didn't mean that s/he thought as already a few incorrect reports, it is impossible to reach 100%. And if Vod knew then why s/he will ask to the poster as the poster will not be able to reply.
Ebay does the same damn thing with their positive feedback %, and thus there are tons of sellers with 100% positive but who actually have some negatives somewhere in there.
I do not think it is a big deal either shows decimal or not. This percentage is not public it is private and the reporter can see how many good, bad or unhandled.
