It got guiltied, yes its been reversed but imagine if I inno'd that report, I'd get a strike against me as judging it incorrectly just because majority ruled it guilty to warrant the ban in the first place.
The only "strike" you get is a -1TR, which really doesn't do much unless you consistently vote against the Juror Guide. Guilty reports that turn out to be innocent happen maybe once in every 500-1000 reports. And even if you do get locked out of voting for consistently voting against the majority of other jurors (and a majority vote is the entire point of a community-driven system), as Levin already explained to you before, you can just contact Levin and ask him to check into it and reverse the lock. Is it annoying for people who get locked out? Sure. But on the other hand, to get completely locked out, in the instance of coming straight out of the tutorial, you would have to vote against juror majority more than 12 times in a row. This is why we often refer new jurors to the Trial Server Discord as well, so they can get some tips as to how to stop that from happening consistently, because, as it is widely broadcast: It is a system where the majority vote counts and someone going against the majority vote enough times to get locked out of the Trial System more than once is usually either not understanding what they are doing, committing vote fraud, or voting in categories that get handled/punished way differently than they would think. Often this is solved by simply reading the Juror Guide and Rules Guide, as well as talking to fellow jurors (and staff) in Discord who generally advise people to take the "easier" categories as a start as to get a bit of a buffer for votes that cost you TR.
Regardless, this is an "issue" that only you seem to come across, people that get locked out of voting are few and far between and usually only have it happen to them once.
As for steam, no, we did not have to create anything when I bought the game years ago, we created a user name and that was it
The only Steam accounts that didn't require a register were back in early 2015. Those users still had a username, or could have contact anyone without any issues on Steam Discussions, or through support via e-mail (or via a support ticket on the website). Currently, there is not a single ToS player that does not have to register, let alone cannot register. This is not a staff-related issue, nor is it a forum-related issue. This is an issue of not being able to help people who do not contact support when they do have a problem. Heck, even if you have problems logging into the forums with an account that does not seem like it's registered on the forums, you get an option to "Contact the Board Administrator" with which one can send an e-mail to the Board Admin to have their problem solved.
The majority of people logging in under a different username on the forums for say an Appeal, are people that simply do not know their ToS account password, or don't realise you can log in with your ToS account details. Which is why we point out: "Please log in with the banned/suspended account."
We can't read minds, if people don't contact anyone with issues, there's not a lot we can do, and being preemptive about every little thing that can go wrong is generally a waste of valuable time, because the time we spend helping someone who doesn't need said help, is valuable time we lose to help other people who do need help.
Take the section reporting players for example, goes unanswered for a long time when people report players, they've been harassed, upset by a player and come here to log that experience and have action taken but no one knows what happens next, has their report been read, what happens next, what action has been taken etc.
Every post in Report Players subforum gets answered when handled and moved to "Closed Reports". Every poster (and every member on the forums) can see/follow those posts. The Judges handle those reports within a day (unless there's unforeseen circumstances that render it absolutely impossible for any Judge or Trial Moderator to be there) and they even let the poster know with a reply whether the user was permanently banned, suspended or if the report did not follow the guidelines.
