These objects they bought illegally, were not bought by chance or "luck", these objects were sold for illegal pages in dollars.
Second:
You call themselves "pro-players" who have been in the game for years and will say they did not know what they were doing was illegal? It was clear to these players that these objects would not be available until after 24-25. 1 coin per week, you need 25 = 25 weeks, it was well known that this but they decided to ignore it.
Third.
In any case "ignorance of the law does not exempt you from it"
Fourth:
Some of these players say they only had the object for a short time, this is just as serious as having bought it directly ... They should read the rules of the game and understand why they were punished too.
Fifth and last.
Having already discovered that these pro-players were willing to break the rules of the game for better objects. How can we know that they did not do it before?
Best wishes and I hope that the investigations clarify things a little more, good luck and good game.
