Today the internet is full of unwanted ads and scams, here is a list of sites I personally block to reduce my frustrations while browsing online. 
I simply use my routers function to block these sites, I don't recommend any software to do it though there are several, it's up to you how you block them but I have several devices and it's far easier to just use the settings in my router to do this.  If you go that route you will need to consult the documentation on your router if you do not understand how to do so, just have a look on the manufactures website, any router than isn't 15+ years old should be able to do this.
I will update this list every so often and will just continue adding to the list.
