Bright Data does a much stricter compliance on its customers than a regular ISP so the likelihood of abuse through its network is much smaller.
However it's actually not relevant because the AUP of the user`s ISP is between them and the ISP. In the slim chance that some illegal activity goes through the user the ISP AUP is not breached by the user but rather it`s a third party that breaches the Bright Data`s license agreement.
Much like British Telecom P2P Wifi where users share their home Wifi with people on the street, Bright Data network traffic is logged and so the user will never be accused of anything they didn't actually do.
Does a user with "Bright Data" App installed breach the AUP for their ISP?
