Are they known to throttle high usage ? <| sep |> Not illegal in provinces with sane lawsbut hey SJTribunals exists and there you are guilty till proven innocent and you pay for your accusers lawyer win or lose , so there ' s no telling if your province has sane laws . Sharing the connection is probably a violation of your terms of use . Do not leave it open . Use a DDWRT compatible router . Set up a list of blocked sites . You can find list of porn sites and the like and their ip addresses to put in . You should also list the permitted devices by mac address so ONLY those devices have access . DDWRT will also allow you to set up other controls like Advanced QoS Quality of Service controls for bandwidth allocation to your various Network connections . Viewable performance graphs and statistics to watch your network performance and measure your bandwidth levels . You are NOT legally responsible for everything that comes across it any more than if a son or spouse did something illegal . Being accused however can be a legal nightmare until the real law breaker is identified . That ' s why you need to block sites . Or block everything except permitted sites .
