I totally agree that VMK has flipped out with this "warning" people for entering too many codes, or for entering them too fast. They should have foreseen that people would repeatedly play and enter mass amounts of codes for the pirate costume. I don't know what the limits/quotas are that earns somebody a warning -- does anybody?
Yesterday I also got caught up in the quest for the pirate costume, and entered mass amounts of codes. I started out putting the loot in storage rooms. Then I started selling each item as soon as I coded it in. Then I went back to my store rooms and took most of the items out and sold them, thinking the 50 credits sell-back might be reduced soon. I didn't get a warning, and am not sure why I didn't. Here's how I did the "coding" -- I don't know if this is a prescription to prevent a ban, and don't guarantee anything. Who knows, maybe I will be next after I log on VMK today and code for the pirate costume again. Just my two cents on what worked for me yesterday.
I have two monitors set up on my computer. Don't ask me how to do it, my son worked it all out for me lol! Anyway, I have VMK up on one monitor, and the pirate game up on the other. I put my character in one of my storage rooms. I DO NOT place her in a public area of VMK. I play the pirate game using the shortcut to get the codes. When a code appears for the pirate game, I just input it right then on my VMK character. I get another code, then input that. No having to write down any codes or copy and paste into a word document. I used the codes as soon as I got them. I deliberately slowed down my typing speed. When the codes failed to work anymore, I switched to a different storage room and start inputing them again. The most codes I inputed at one time was around 25. Then I would take a break, visit other public areas of VMK, go do housework, laundry, real life stuff, etc. I assume this same system would work by just resizing the two windows on just one monitor.
After VMK closed last night, I did stay up and got a couple hundred more codes and DID copy and paste them into a word document. I'll trying entering them slowly today, maybe 10-20 at a time, as I won't have the delay between codes I had yesterday. I guess I'll keep my fingers crossed and hope I don't get the "warning."
