Thought it was worth telling Turbine how EVE Online handles exploits, as they do it exceptionally well and Turbine could learn from this.
First, they have a standing bounty. "Tell us a new exploit, we will give you one month free game time" (which in DDO would translate to 1000 TP or one month's VIP).
Secondly, when an exploit is deemed worthy of attention, they make a public announcement (similar to a launcher announcement) to the following effect:
"Notice of Exploit - There is an exploit involving bags and item duplication. This is a final warning that players using this exploit will receive a permanent account ban". Note there is not exact details on how to replicate the exploit, although there may be enough hints to help someone figure it out.
Thirdly, they enforce that warning. Exploit after the announcement, and you are banhammered. Those that exploited before the announcement are taken on a case-by-case basis - receiving anything from a warning up to a permaban depending upon a GM's best judgement.
Finally, they then investigate trades related to the exploit made by accounts that used the exploit (both before and after the announcement) and revert them.
It is amazing how much more effective this is than the apparent Turbine policy of "Ignore it and hope it goes away." That policy didn't work for the 2007 mana pot duplication, it didn't work for red/blue flagging, it didn't work for trading bound ingredients, and it certainly did not work for the great 2013 duping spree.
