Are you aware of *any* website that is specifically optimized for DDG ?
The whole point of DDG is to not allow tracking of any kind. I don't see any website seeing an advantage to offering a specific DDG version. It's a contradiction.
I'm pretty sure any website that represents a real business is not going to go down the DDG route. There's no reason to do it, and no advantage (to them) to doing it.
This is the kind of place where if there were a DDG "optimized" chess.com version, people would be complaining about having to enter their username and password at every login 
it's just not convenient, and people love to complain without understanding how their choices affect their experience.
I, for one anyway, don't care if I'm tracked by chess.com. The benefits outweigh the disadvantages. By a lot.
-1. Yeah I also have problems about having to sign-in every time. It would just be so much extra work for the developers.
And another thing, @BeastGuy2, you might want to check out the browser Brave
It is a great browser that has many awesome features like ad-blocking and anti-tracking. Been using it for a while.
solve puzzles
Me before solving: Seriously? Was this needed? I must report this person
Me after solving this: Perhaps that wasn't so bad. Maybe I'll go and scratch that report of my to-do list
@Ayushman965 nah, I solved it *and* reported. best of both worlds
Yeah. Totally...
My understanding is that chess.com is optimized for the Chrome browser. That makes it compatible with just about everything else.
I suggest adding a separate for the DuckDuckGo browser. Why? I see the browser as emerging, being relatively new (it was made in 2008). It could be more convenient for DuckDuckGo users, and then start adding new versions for other browsers, like Chromium and Firefox. It would be a lot of work, but it would end up better for the website.
+1 for like
-1 for disapprove (and say why)
