Simple way to get rid of code snippet spam (StackOverflow clones) in Google
As if internet is not already full of bad advice about software development, there are always people who will find a way to make situation worse.
Solving programming problems, might be very time consuming, and to waste your time even more, there are many spam websites, that just rehash Stack Overflow/GitHub issues.
Seems that Google can't (or won't) do anything about it. Situation got so bad, that for some queries you get only spam results, Google is unable to find original.
You can easily found a dozen spam sites by searching any StackOverflow question in qoutes.
To save your time, you can use one of browser extensions that block certain sites from search results. But as I've mentioned previously, extensions are probably bad for you. Plus you need to configure and maintain the list.
As the simplest alternative, I suggest a block list (filter list). You probably already have a uBlock installed (or any other blocker compatible with AdBlock format). Or Vivaldi has built-in AdBlocker (Settings→Privacy→Tracker and ad blocking→Manage Sources->➕).
So, to get rid of search spam,
subscribe to this list.
UPD exactly at the same time I wrote this post, another filter list was featured on Hacker News. So I'm not the only one who is bothered by this problem.
Since it gained more attention, please use it.
UPD2 Neither Google or filter list are able to keep up with the problem. New spam sites keep popping up too quickly. Seems the only way to get rid of it is to use DuckDuckGo.
