Trade Items without being tracked

I am looking to transfer a lot of items between accounts in OSRS and private servers. What type of trading methods are logged? I know RS logs drop trades, trades, PK kill drops.

Are the following also logged in OSRS or big RSPSs:
1) Duel Arena staking
2) selling to shop on one acc and buying on another.
3) GE?
4) Player owned shops (popular in RSPSs)

Any tip is much appreciated.

Bump... I am curious about this too

Spoke to someone who does RSPS dev. Apparently, all the below methods can easily be logged:
GE trades
Duel Arena staking
PK drops
selling/buying items to/from general store
Item drops due to deaths to NPCs

Only true way to transfer things is relative safety is trade between 2 main account (not mules) with different IPs and MACs. You can make the trade one-sided little bit, but not by too much. Funneling items from bots to mains remains painful.
