Just putting this here so people see it and can take action. This is not a netbird issue.
A colleague at work just told me about this and looking at the coturn logs of my self hosted server I did see some suspicious IP addresses in the logs. This is an issue for the coturn people to figure out but it's probably a good idea to disable coturn in your setup before your ISP or vps provider bans you. As far as I know netbird only uses coturn for fallback so disabling it should be fine for most Users.
See the link below for more information.
