Earlier I used the hosts file extensively on my devices to nuke time wasting web sites from my work zone. On Mac I also used to use a program called vitamin-R which helped me somewhat back im the day, but it doesn't make the computer less distracting, only helps me cope with it. (Yes, it still exists, I was pleasantly surprised that it still existed when I got a Mac mini last year after being away from Macs for almost a decade. Now if someone could recreate Alarms, the visual countdown program I used until it broke on Snow Leopard I'd probably happily pay for it again.) With reference to toxic forums, as the saying goes: it is not a problem if the submarine is in the ocean but a big problem if the ocean is in the submarine. Stick to places where your hull tolerates the pressure and where you can do something useful. I've seen plenty of nasty posts the places I go and I can also say I and others have succeeded somewhat in flagging and smacking down trolls and (actual) nazis that at least one place that used to be ugly is now somewhat safe (i.e. no complaints anymore about Hitler dying to young after articles about the middle east).
