Totally off topic:
Free users may be interested in ADGuard they have free addons for firefox, and I am sure other browsers, but they also have software that you pay for that can be used to block for your whole device, You have to go to their web site to download it.
For the people that want to stop other people from seeing where you go on the internet there are VPN's. I am using IPVanish, they are having a sell this month. I think I saw some other VPN's having sells this month also. To be honest I have only used it for a week, but it was easy to setup just download their software.
Come see me at Systematic Investing group #board-966 lets talk formula plans.
