Where do chess.com puzzles come from? just curious

hiii guys I am just curious, cuz i often do puzzles on both chess.com and lichess.org

(that was before i lost my diamond membership this April)

anyways i think both site's puzzles are great, but chess.com puzzles seems a lot more ideal, so i am just wondering whether chess.com hire staffs to make them up lol.

cuz i know lichess just grabs puzzles from real games (it literally gains like a puzzle in its database every few minutes from players contributing online in games lol)

the real cool thing about lichess is it actually allows you to know the puzzles you contributed (like on https://lichess.org/training/of-player it shows you puzzles extracted from your games)

idk if chess.com can develop a feature like that as well

then it will be real cool

and also title. 

U will get banned for promoting lichess

LOl but i really like lichess puzzles cuz they are free and great (real cuz they are from real positions)

so i kinda feel guilty that i seldom play games there, contributing nothing to its database though doing thousands of puzzles there LOL

Most puzzles are pulled automatically from games played on site.

That may be true , right?

You should do chess tempo instead. Lichess puzzles comes from random lichess blitz games while chess tempo puzzles come from real OTB games

and chess.com puzzles are just artificial puzzles.

this is why I recommend chess tempo. I got more than 400 rating  when I started doing chess tempo. For playing, I recommend chess.com or lichess, but for puzzles you should do chess tempo.

Jesus makes the puzzles.

they get it from the puzzle god or they just use a random machine
