Late, maybe, but I was just in FFG's chat (yeah, yeah) and a few people super chatted her about Brooke and Karate Joe. That triggered a memory. In her stream today, whilst reminiscing a bit about Karate Joe, Chinny mentions his cat Tater. A few days ago, one of her favorite VIBs Brooke announced it was her birthday, and whilst I wasn't reading the chat at the time, I remember Chins saying something about Tater. She seemed confused and stumbled over her words a bit before saying, "I'll tell you guys later." Even at the time, I suspected it, but I had no way to connect Tater to Karate Joe. She just tipped her hand once again. Thanks, Chinny!
If I can find the clip, I'll post the transcript, but even without it, I'm convinced Brooke is 100% Karate Joe.
ETA:
@Rotogravure might be right, but that's a hell of a coincidence. Besides, Chins' reaction was so bizarre. That's what tipped me off days ago. The coincidence now is just too much. I'll find the clip and investigate further.
