This is a huge issue- reports seem to auto ban from voice chat. I documented my experience with this issue here and it received almost 50+ likes and yet Roblox has purposely ignored the problem.
Please acknowledge the issue and remove the false moderation history from those who you have unfairly banned. It is astounding that Roblox has ignored and left this huge flaw in their system. Not to mention the fact that appeals team refuses to review or provide any context
