Boards Bug / Riven's W Bug

Boards Bug: I recently changed my name to Kyster not too long ago maybe, 2-3 months ago and I have seen some posts about Kyster from 2-3 years ago. I did not make these posts but, the person who owned the "Kyster" name before. That also changed all my reported bugs. I used to have, "WellHungWhiteGuy" as my username and now I can't see all my bug reports and anything anymore. Meaning, all my posts I made as, "WellHungWhiteGuy" have been changed to posts about the previous owner of the name "Kyster." I need help with getting my old bug reports back and so on.

Riven's W Bug: I don't know if this is a thing or not but, if you are stunned by riven during an animation of the auto-attack is it suppose to cancel the auto-attack or not because, I stunned a Xin-Zhao as Riven during his auto-attack animation and it still damaged me after I stunned. I was wondering if this was a bug or it is normal..
