Blitz games are better

Not likely. A lot of players make far fewer mistakes and see many more good moves when they have more time to choose their moves. And too many players just play the first thing they think looks good without bothering to think too deeply.

It depends who u are.
When I first started playing chess, all I did was blitz, and I went from 600 to 1800 in about 2 years just from that.

I think the major reason why here people tend to have higher rapid rating (at least up to let's say 2 000 rating) is because titled players rarely play rapid time controls. So the distribution of points in that pool is probably more even. In blitz time controls, titled players compete a lot and take a lot of rating points from lower rated players. And the weaker you are, generally the bigger difference between your rapid and blitz ratings will be. There are exceptions of course, but on average it is like that.
On sub 1 000 level, cheaters are pretty rare occurrence by the way. On top of all that, people cheat in blitz as well. So you are miles off in my opinion.

Ah, yes... players cheating in order to gain that coveted 1100 rating.
Now they must be the envy of their peers.

Blitz cultivates error.
can confirm. I spent 17 minutes in otb 90+30 trying to remember how to draw a philidor position (rook 2 pawn vs rook 1 pawn, but i was about to trade a set of pawns). I remembered, played a move, immediately dropped my pawn so he had two connected passers and i lost. I had 50 minutes.

ha I kept that ratio up until 1800+
that just means they improve more than they play... or they take the time to avoid tilt...

What about those who win nearly 70%?

I am 2100 in blitz. And I have only 51% winrate..

My blitz win rate is 47%. For most of the past three years, my total losses exceeded my wins, but I turned that around this fall.

People cheat more in longer games, that's a fact, simply because there is more time to cheat. Still you should play longer games if you want to improve, because blitz just doesn't improve your chess like thinking for real does.
Report clear suspects and block even the slightest suspects is my recipe for rapid chess, then just go next game, or take a break if you are annoyed and go next when you feel like playing again.

There are less people that cheat than you'd think. Around ~2100 rapid here I encounter a cheater about once every 20-30 games. So about a 4% chance.
Basically, if you can reach X rating legitimately why can't others?

Oh crap this means I’m cheating
