Alright, even if this isn’t actually saying it’s about a ban appeal, it is still about a ban appeal, so the information forum moderators have on this is limited.
We do not have access to methods, processes or anything else used by the team in charge of appeals.
That being said, they review all information available on the account when implementing or reviewing a ban. In some cases links to external websites may not be accessed if deemed a security or privacy risk, but I cannot confirm or deny that this is the case here, since that is information only the team in charge of this would handle.
I must stress that mass reports by themselves do not result in bans. The team in charge reviews all reports and then investigates what happened. If a ban resulted from this, then evidence of a breach of the code of conduct was found by the person that reviewed it. If the appeal is denied, then evidence showing that the ban was warranted was also found by investigating all of the account.
