Yep, I was experimenting to determine if the hot algorithm was game-able.
I did bring this to attention in my post where I discuss how crazy stupid sybils currently are. It's an important topic! I encourage you to read the sybil section in that post if you have not, yet.
I admit to it in my post:
if I want to upvote with all my VESTS, I cause a sybil attack and can immediately start trending on hot (it is quite silly)
I also responded to william banks explicitly saying I upvoted myself 100 times. (Ridiculous, right?)
