是否有免费的无日志vpn？
most free vpns come with hidden costs - like the risk of data logging. some have even been caught selling users' logs to make extra money. even if they claim not to log your data, free vpns don't have the resources to invest in an independent audit. so, you never know if they're telling the truth.
