Is anyone able to help me understand #roblox?

My children enjoy playing, but both of their accounts were suddenly banned (or deleted?) today and we don’t know why.

I sent an appeal but I have two sad kiddos. I don’t play and I’m not familiar with how it works, but I’d appreciate any insight on this or suggestions about how to get it working again. #gaming

I just searched and found a forum post dated February 16 where the poster had their account banned, because they accessed from the same Wi-Fi his brother, who had been "legitimately banned," and Roblox assumed the poster's account was actually the brother trying to dodge the ban. I doubt yours is the same situation, but two accounts on the same IP address may have triggered the bans?
@RachelThornSub
If one of the kids was reported for griefing or something, maybe the other would have also caught the ban? Two accounts alone isn't likely to result in ban, lots of people play with their parents or siblings or friends
