Not any that I know of, a lot were patched.
Just buy a bond, they are only ~7m, and it's permanent
My input might be completely ignored, as I'm not 100% sure but put the money in your inventory and get killed in red portal? Maybe? I'm not sure, don't try and blame me as you may lose your GP. :S
They reinstated the cap?
I honestly wouldn't understand why wildy / portal kill wouldn't work.
That would be game - breaking level for jagex if you killed someone in risked item combat and didn't recieve your loot due to them not having a membership.
Try the portal.. I've used it before and I'm sure it still works
