A big part of chess is that you get confronted with yourself, and you need to learn to lose gracefully if you'r going to play. In a way, you not only need to work on your game, you need to work on yourself too.
Why is Online play SO UNFAIR?!

For a few minutes, I'm on a winning streak and JUST got to 800 points and am intrigued to get to 850! But then, SO SO SUDDENLY, someone SO GOOD comes along and COMPLETELY CRUSHES ME. CHESS.COM CAN SEE I LOST THAT ONE, so did they give me an easier opponent? NO, THEY DID NOT. I WON 3, BUT LOST ABOUT 10 IN A ROW!!!!! HOW IS THAT FAIR?!?!?!
You cannot win every time.
You don't play against everybody on the whole server, only a limited subset. Therefore, your rating is far off from other players that are not your immediate opponents.

Life is unfair.😢
That's why I say "Chess is as fair as it gets." Very little, if anything, in life is as fair as chess. If a person whines that chess is unfair, I don't want to know what he thinks about other aspects of life.

....
Online it was just brute force "it's ALWAYS a check or capture." I assume that's how some really bad players have super high puzzle ratings... when the moves are always extremely forcing all you have to do is guess which check or capture is right.
...
This is not true. There are a lot of more complex puzzles in the system.
same as me lol
760 rapid and 2300 puzzle XD

This is very normal. Ratings don't equal strength. You can be an 800, and get 800-870 rated opponents, but your opponents can be underrated or overrated. If this upsets you, you can always set your opponents' minimum and maximum ratings. To do this, go to the play section choose the time control you want to play, and click "Custom". There you will see "Rating Range", edit it. You'll get opponents in the rating range you set.
thanks

this is why i think chess.com is unfair. They made me matchmake against 1300 players when i was 700. Then i lost more than 150 elo cause of that, then i saw that when players won against me who were similar elo. They got 21 elo when they won and when i win i only get like 6 or 8 elo. This is why i think it is very unfair

That is because you do not understand the rating system. Chess.com uses the Glicko system, not straight Elo. There is a second component that judges the statistical reliability of your rating and when you are new or haven't played a time control in a while, the changes can be larger.

Rating doesn't equal skill, proceeds to suggest rating related hacks. I've seen it all at this point.

This was years ago but the point I was probably trying to make was that if you want to maintain a certain rating or win as much games as possible and go higher without getting affected by the chess.com's rating and challenge system—if you read through the OP's post without aggression or bias that are directly influenced by your negative experiences, you will be able to identify that chess.com's pool system, the result you had in the last game you played and game-following-challenge-player-rating correlation is what originally frustrated them—you can try (success not guaranteed!) to artificially manipulate the following game's opponent rating in a way that won't make you lose 50 points and rage and pick on other people's suggestions to solve the issue from two years ago.
When I was new to puzzle rush I had the same problem... there were times I'd spend a few minutes calculating on a 1200 puzzle, because the full solution was actually really difficult... but of course if you play the random scary-looking check you immediately get it "correct" without needing to input any more moves and you move on to the next one.
