I wanted to access someone's website who is using "x10.mx" domain name and Brave web browser has blocked the domain name and says that it maybe "risky". I tried to just access x10.mx and yep it is blocked.
There isn’t much that can be done about this. This is Xfinity Advanced Security in place. Options would be to either disable it or report it as a false positive to Xfinity and at https://spa.xfinity.com/report and reporting to it Brave.
