AssassianKD responded back with quite the rant over being contacted that his spamming was brought to the attention of Bandai/Namco:

What is amusing about this rant is he states he states I don't know him, but his response pretty well says it all.  There is literally no punctuation in this response, so it's likely a kid still going through school.  Plus the language used shows that he was doing this on purpose.  Also he stated that he's string of spam wasn't that bad; the screenshot taken of his spam is only rivaled by perhaps two spammers I have gotten visual logs on so far & those were bad enough I had to get videos for them (I started recording on the run of spam from this moron also, which would have been uploaded to YouTube & linked over if not for the fact that I decided I could fit it all in a continuous screenshot; the two that rivaled this idiot had to be videos rather than screenshots, because their was no way I would have been able to get all those screenshots taken before it started scrolling off the top of the chat log in the game).
