"he said that he sold his profile"
"He didnt, but its obvious that this was done"
-> All you have is your imagination and assumption, on things that you wish to be true. We already have a case where Valve has removed a VAC ban because of the evidence the player provided. Question is why would Jamppis case be any different.
"That the full court case does not contain any single word and information that already then in 2014/2015 he somehow actively denied his innocence, like messages to steam support"
-> The court case states that he bought the account to his friend (he bought multiple accounts to all of his friends with his fathers credit card). He surely broke the ToS in multiple ways because nobody actually reads that, but even if he knew that his friend cheated and got vac, which he might have not knew at the time, from his point of view that was his friends account and he had no need to make any requests to support.
"They do, they can compare old one account with vac and new one, which also belong to jamppi. Like all linked steam account with this IP address."
-> This is true, but there is no evidence on that this has been done. Also like stated it is possible to have same IP address if you are in a LAN party as he stated. This evidence is exactly what Jamppi is asking from Valve to provide, to explain if they did do this type of check and what is the record from Jamppis accounts if they did. There is really no reason for Valve not to release this information and by EU law (GDPR) they have to release the information by request - thus the lawsuit. But like said, there is no evidence that this type of check has been done.
"Also, i didnt banned Jammpii, valve did. I think this is their own rules and they know better how to deal with laws and their own ToS"
-> To be honest, all that is known of the whole case is that, VAC has banned an account for cheating, that account has been bought by the same person who has bought Jamppis current account. There is zero evidence in any direction, Jamppi has made a statement breaking ToS, but Valve has not really responded in any way, the only evidence that has been provided is that Valve has checked that yes these accounts are bought by the same person thus denying access for Jamppi to attend events.
"He also began to pretend for lifting the lock only after he joined the organization ENCE and as soon as he smelled of money. Don't think too many coincidences?"
-> Pretend? Dude you need to learn more english. He was a professional player already signed by SJ Gaming and this account issue came into light as he was trying to get into FPL, faceit made the investigations and allowed him to play. At the same time he started requesting information from Valve as he was in making of a deal with OG. Valve sent him only one email back not clarifying anything, just stated the obvious that the accounts are linked by the same buyer. After this he got kicked out of SJ Gaming and he lost the deal with OG and he sued Valve because they have not been responding anything to him.
He got a deal with ENCE a lot later and that has probably made his lawsuit even worse. They have stated multiple times that money is not something that they are looking for, they want to get the ban removed and to be able to do that they need to prove their story, just like robiin in the OP has done. It took robiin 5 years to get response from Valve.
"You are simply ignoring very tiny but very important things."
Really? I'm not lying and inventing thing out of my ass? Is that the important things that i've been ignoring?
You have jumped to conclusion that Jamppi is a cheater, which is your right, but to invent "evidence" around it to justify the conclusion is what is wrong with this world. Sorry to say that you are part of the problem.
