How do you make the difference between a contestant who finds such an item and buys it legimitely in the market and the following scenario:

- I am a contestant and I have a friend using a different account (different country and IP, but VPN could be an alternative as well)
- I ask that friend to put at sale a '[INSERT ANY VALUE ITEM LIKE Void Force]' for a very low price. I send him usd through paypal in exchange for that. Could even be a Hunter Force at 2k instead of a Void Force at 5k I will insta buy it once it appears in the market so no one else gets the chance to see it there.
- I put the Void Force at sale for a slightly discounted price (in comparison with the usual price) so it sells fast in the market.
- This process is basically buying TC and from there I will have a big advantage and ruin the contest. Will even make a lot of profit since the big prize is more valuable than the USD paid for the Void Force.

Also, how do you handle cases where people place overpriced items in market and their friends buy them? This can be abused as well, and it only takes 1 2 transactions in the start of the contest to get a huge unfair advantage.

You can vary the scenarios with different items/prices, but the idea remains the same.

How do you ensure market transactions like the ones mentioned above are not a cover for a un unfair paypal transaction?
