What the rule says
This question needs a clear answer, because there are plenty of sources on the internet saying both "it's allowed" and "certain ban". Neither is right. The truth is: it's against the rules, and the sanction is at the company's discretion.
Article 5.4.c of the Metin2 General Terms of Use forbids the user from: using virtual items used in the game outside the game, buying them for real money, selling or trading them.
Article 10.3 lists the cases in which Gameforge can terminate the contract for good cause, and buying and selling virtual items for real money is among those reasons. Terminating the contract in practice means closing the account.
Also, under article 2.7 the account cannot be transferred without Gameforge's approval. So "I bought an account" leads to the same door.
What happens in practice
- Buying and selling yang on its own isn't an automatic ban reason; the system doesn't read every trade and hand out penalties.
- Accounts that draw attention can be investigated. Bulk sales well below the in-game market price, unusual trade volume and reports are the things that trigger a review.
- The penalty can go as far as closing the account completely; partial restrictions can be applied too.
- The source of the yang matters as well: when yang produced by bots or cheats enters an account, that account can be pulled into the investigation too.
- Gameforge opens ban amnesty programs from time to time, but keeps bot- and cheat-related bans outside those programs.
Things that lower the risk
The following don't remove the rule; they only lower the chance of things going wrong. You make the decision and you carry the consequence.
The biggest risk is losing your money. Because it's a rule violation, you can't complain to the game company when you're wronged. That's why established sellers with payment protection that have been operating for a long time are preferred.
The second risk is the delivery method. A very large amount in one go is a transaction that draws attention. Buying in parts leaves a calmer profile.
The third is price. An offer well below the market is usually either a scam or yang that isn't clean.
So what does this site do?
We don't sell yang. We collect the prices the seller sites list and put them side by side — who sells at what price, who buys at what price.
We don't hide the rule either. That's why we wrote this page: people search "is it forbidden" and deserve the right answer. The decision is yours.
