Mindless mudslinging ftl
I can honestly say: It doesn't matter if it was RP or not. The fact that it happened SO long ago, and also the fact that when the new master server is active everyone will be unbanned anyway, there's no sense in arguing over it. Just wait for Light to RP again, and then report it. Simple.
But yeah, it looks like RP to me. "Making you feel better" CAN be a scene; maybe in a romance movie or something. Also, I highly doubt someone stole your name and was impersonating you. The fact that you brought it up, and are a person being so defensive about it only reinforces the fact that it was you. Regardless if it was you or not, it would still only be Light getting banned, not you.
Since Light said "i don't even care because i'm retiring", doesn't that mean he doesn't care that the event happened? If so, he should just be banned until the new MS, then. Like he said, he doesn't care.
Also, yeah, Amy Rose RPs a bunch. What a coincidence that she's involved in this discussion about RPing!
By the way, I don't think it matters at what time you report. It was still on the Master Server, therefore it is still valid.
