1.) Just 6 hours later and you're already pushing your thread?
2.) I wouldn't do that. In best case your push post is deleted by the mods, in the worst case your whole thread.
Hm, I don't know if there is a rule or not. I just saw that happen a few times.
And to be honest: Even if there would be a rule, 99% of the people wouldn't read it, right?
The rules do say "Please note that excessive bumps will be deleted and possibly the thread itself."
Granted, it isn't defined what counts as excessive, but after only a few hours definitely qualifies in my opinion.
As for the video, she's only listed as Ayano (あやの)
