There was a banwave today and a lot of people were affected. More info on this v3rm thread: https://v3rmillion.net/showthread.php?tid=981123
Yes, this ban includes paid exploit users (I got banned too)
For me only one alt got banned. (That too just cause I checked if Proto was actually detected.)
Seems like roblox decided to revert this ban wave after the amount of false-positives that it caused.
