I have had a problem very similar to NickoSCP’s.
My account was also terminated a few days before Christmas Day of last year with no warning. Despite being on Roblox since 2011 and being a small/medium sized developer (my game has two and a half million visits with 75 players at the time of me writing this), I was not able to have my termination addressed through the appeals process, either. I can only assume that I was banned because of my group, but my termination page does not even have a moderator’s note or a reason why I was banned, so I can only guess.
My group is/was a Confederate Army (American Civil War) war group/clan. At the time of my termination, it had been operating for over ten years. Yeah, ten years. I have ran it since 2013. Due to the subject of the group, I and my admins controlled any misbehavior to the best of our ability, and due to Roblox’s community guidelines, my game has not had Confederate battle flags since they were banned a couple of years ago.
Like NickoSCP, I wasn’t given any warnings, either. Since my game was left up, I can only assume Roblox no longer wants Confederate Army groups, but I was not given the opportunity to rebrand my group, or anything like that, as I would be open to doing so. Instead, my eight year old account, around 45,000 Robux/lifetime Premium, and my over ten years old group were terminated.
I agree completely that things like this greatly shake the confidence of developers on Roblox. My game has millions of visits, and I have not been able to have this fixed for nearly four months.
I completely agree with Cindering that the appeals process needs some kind of reformation and that there needs to be additional safety checks before lengthy bans or terminations are given out. More ways to have an account unbanned in situations like this, as NickoSCP suggested, is probably an excellent idea, as most developers do not have the ability to directly contact people who can fix moderation issues on our accounts, as Cindering explains he had to do.
I expect what Cindering said about us being critical about the moderation system because we are passionate about Roblox is the truth for all of us; certainly it is for me, given that I have been a player on Roblox for almost a decade.
