So, the time goes by and I was hunting (Grenwalls), never seen a player hunting, but then one day I log in and find out that player hunting on my spot.
I was like:
... a player here.
So I greet her and all the stuff, she kept hunting.
So I tried the bot-trick (lay down box trap where bot's are, and they'll try to pick them up or something).
It was bot.
I decided I'll check her/his HiScores as often as I'll be able to, and here are some results:

(date (time) / Hunter XPs (Hunter rank)
21-Jul-2011 (15:06 GMT+1) / 43,867,141 XPs (335)

23-Aug-2011 (11:08 GMT+1) / 85,237,841 XPs (81)IN A MONTH (SINCE START OF THIS LOG), THIS BOT GOT JUST OVER 40M XPS. THIS IS APPROXIMATE 1.3M XPS PER DAY (APPROX. 14 HOURS OF GAME-PLAY PER DAY).
As you can see, this bot gets approximately 1.2-1.5M XPs per day (that's about 17-20 hours of play-time).
This bot also gains approximately 30-35M gp per day.
Another evidence: all her/his XPs logged on HiScores (updated) are ALWAYS rounded to xx,xxx,x41 XPs - how can real person do that...
Ps - this bot has been reported by me 3 times - no actions taken by JaGEx so far.
I'll keep this log updated as often as I'll be able to
