well, I quess they are sure that it's happening and maybe they could see by who. Maybe they can check it in their system and see how many times people wear sara/zammy pl8's and gets killed, not sure afcourse.
They know RWTing is still alive through Bounty Hunter, but what can they do? The only way to completely stop RWT is by removing any and all things PvP from the game, which they know they can't do as they would lose too many players for it to be ignored.
JaGEX will already know that RWT is going on (Like others have said). Although in my opinion, I think they're scared to do anything about it. I mean, they've already lost a handfull of their customers due to their recent updates.
JaGEX have a major decision to make:
1) Close BH, and stop RWT.
or
2) Keep BH open, and keep their few dedicated users.
Guarantee you they already know. They also know that there's pretty much no way to stop RWT'ing without taking out any sort of item/gold exchanging system.
Exactly, and what the other posters said is true, they can't ban you for dying in BH, I highly doubt they will shut down BH, all I can think of a is a cap to what amount someone can bring in.
If theres a cap people just do smaller trade increments and yes they have I was going to say same as xix said about easters
A cap would just lose more players really
