There seem to be a growing number of websites containing an automatically translated content. Now, there's nothing wrong with that per se, as long as you find what you're looking for, but I'm yet to see well machine-translated article. They can mostly do the title right, some sentences might even make sense, but overall, it's a disaster.
I always block these when I encounter them, so here are some examples:
I don't have specific queries, but you can easily find them by just copying keywords into Kagi. These are just random pages found on them. Every single one of those is an automatically and badly translated website, usually from Russian, but other languages such as Spanish or French are no exception.
I can mostly spot them pretty fast just by looking at the URL - I specifically encounter such results with queries in Czech (but I know for a fact that most of these websites are translated to Slovak, Hungarian, Polish and probably other languages as well) and usually don't expect a never seen before domain with .com TLD (this by the way is interesting, given where from these sites originate - it always seems to be a .com) or containing non-czech/non-english words with /cs/ prefix in path.
I recall Google giving me such results as well back when I was using it, so it seems to be a common problem.
Is there any chance of filtering such results out?
