This issue was addressed a long time ago.
Mugging someone to take their cash is part of the game. If it's not wanted, then it can be removed from combat options. But it is definitely part of combat for a reason -- those who carry a ton of cash will always be at risk.
I know people don't like having things taken from them. But I don't think making the market completely riskless by putting all cash received immediately in the bank is the answer.
You cannot see who's selling credits because people wanted something a little more anonymous. It can't get more anonymous than that, but there will always be someone who gets a lucky mugging in and swipes 65K in one hit (or two).
I can see a solution that would be considered a posting option.
- All postings will be with the person's name listed.
- If the person posting credits/items on the market wants to remain anonymous, then it will cost them a fee.
- If the person selling wants the cash immediately deposited into their bank account, it will cost them a transfer fee.
We are entering our ninth month of operations and there have been 35 muggings that netted the attacker more than $5,000 in cash. 17 of these were due to 1 player who has been retired for awhile. So in 258 days there have been 18 other attacks that resulting in $5,000+ cash being taken. Since there have been over 100,000 attacks, this is almost so rare that it's a wonder why the option is still available for combat.
