This is to be handled by BattlEye. Any post or mention of it in our support channels would be redundant and out of scope.
Talking about it in our general channel is fine, but not in a support context.
We're aware of a large ban wave that happened over the weekend.
Please be mindful that anyone claiming to know the reason why players were banned is just speculating. For example: the certificate issue and workaround wouldn't have led to a ban, nor would other common speculation we've seen.
If your ban is illegitimate, the best option is to submit an appeal to BattlEye directly. BattlEye Support can review and lift your ban if it was applied incorrectly.
