Okay, I just experienced something a little fishy, but, being skeptical I went through precautions and avoided losing my whip.
A few people may not be scam aware so I took it upon myself to get some information from my "lurer" to find out what exactly he'd tried to do to me.
He'd approched me in Ardougne Bank, and asked me to help with a "maxing video". He said, just bring a whip, and when I get you to about 20hp, I'll give you 800k (800k were 4, noted battleaxes).
Here's a chat shot.
It's pretty nasty and I'm not sure whether it's bug abuse or not - but be careful.
(funny thing is, he asked me to stop attacking him since I was owning him XD)
