How to ensure safety by lending others to play?

I'll teach you the best way to make money is to brush Guangyu coins. At present, there are only two ways to brush Guangyu coins: 1. Steal someone else's ADSL account password to buy a card. Although this method of brushing black spots is used by many people, it is risky. Brush 3000 yuan is easy to be found out by the network police. This method is also more troublesome to operate. 2. Take advantage of the loopholes in official website's front desk and sneak into the SQL database in the background for unlimited charges. Now let me explain this method. First of all, I prepare a point card myself (of course, it is not necessary), which can be used in 30 yuan or 50 yuan. Easy card or official card can be used, and then log in to the recharge page (explained by the sound of card clicking) to recharge. Be careful not to write your own account first when entering an account, but must write gmuser32 first (I believe that friends who have played the question know that this is the test number of GM), which is also a customer service inquiry function in the background of the webpage. Then enter the card number and password of the recharge card, and fill in the account password of the recharge card you prepared. Then click OK to start recharging, rest assured that recharging will not succeed, and then log on to the recharging page (the click on the card is clear) to recharge. Pay attention when recharging your account. Don't write your own account number before entering it. You must first write gmuser32. I believe that friends who have played the problem know it. This is the universal test number. This is also a customer service query function in the background of the webpage. Then enter the card number and password of the recharge card, and fill in the account password of the recharge card you prepared. Then click OK to start charging. Don't worry, the recharge will not succeed. If you recharge on other websites, it will be said that it is an account recharge error (in the form of this website). At this time, you have succeeded, because now the number of cards in your hand has tripled! This is the irretrievable 3-base (3*) vulnerability (because it was created with the help of South Korea, but Korean technology was required to evolve into a vulnerability in China, so I won't go into details). That is to say, if the card you ordered just now is from 30 yuan, and now it is from 50 yuan, this is the test number returned to you (due to the mistake of recharging your card, you asked GM to return the money in your card, but 30 yuan, who was supposed to return it to you, became 90 yuan due to a loophole in the problem). You can repeat that, so it's 270 yuan. You are recharging your account, and then you earn 240 yuan! (Generally, just repeat it five times. Too much GM will be difficult, but you will never find it if you brush it five times. Even if you brush 10 times, it's okay. I tried, because GM has no evidence and reason, and it is GM's fault. GM can't do anything. If you take action, you are just trying to solve it. Of course, there is no way to repair it, because the system has changed and the requirements are getting higher and higher now.
