Zero and a lot.
how many people have you blocked or reported

No idea - Lost Count. This site is loaded with jerks! And none of mine are for being called a sucker. If I did that, everyone on the entire site would be reported! I only report more severe stuff, and yet still, too high to count! I've gotten the "MF" name from people many times. I've also been told to die, drop dead, F my mother, eat "brown stuff", and the list goes on!

A lot and a lot. I have to say that I only rarely encounter people who are rude to me but when I suspect your skills are of the downloaded variety then I will report you but also block you.
And how exactly do you determine that? Not all 1800 players play at an 1800 level at all times. Not all 1400 players play at a 1400 level at all times.
If I am playing in an over the board game that features a French Defense (doesn't matter if I'm Black or White), and you saw me play, and you tried to conclude based on my Chess.com Blitz rating, you'd think I was cheating.
If I am playing in a 3 0 game with a Scandinavian Defense on the board (would only happen if I'm White), and you saw my play, you'd think I cheated to get to 1900 blitz and that I'm really only 1400!
So I am going to wager that you have "suspected" many innocent players!

Yea but have ya gotten death threats? Told what a "snitch" you are? How "Uncool" you are? Or what an "old guy"?

I blocked and reported someone for being unsportsmanlike and calling me a cheater when I was very obviously playing mistakes and blunders. He said he would report me and I genuinely got scared and told my parents. Only later did I learn that chess.com doesn't ban you just cause you were reported
I have reported 3 inappropriate people. 1 called me a sucker and another said where I live sucks and I am a loser. the other was random. someone who played me in bullet( I don't see people's usernames during bullet. it wastes a little bit of time) texted me not in chat and said bad language. other people just waited a while and aborted(it is very annoying)
