Since this thread is all about conspiracies, here's mine.

In 10% of the frontlines matches I'm in (as Maelstrom), this conversation appears as part of the strategy:

"Let's rape Kan-E!"
"Yeah!!"
"Yarr"
"Raaaape!!"
"What about Nanamo?"
"Uhh, don't say that out loud?"

So maybe, just maybe some people took it wrongly and thought we're allied with Flames.
