I don't know where you live and which server you play from, but if what you say is true then wherever you are is lucky enough not to have many cheaters.
I'm in Vietnam and playing MM is hella bad. Whether it's vietnamese or chinese hackers (I'm talking blatant hacking), more often than not I would have at least one in the game. My friends have the same issue.
Then again, because of that issue we haven't played MM as much anymore so perhaps we're just unlucky, but not a single spinner or wall hacker in a year would be a miracle still.
Trust factor wise - unless there is a way to check and see it like in Faceit, that argument is just invalid for me. As far as I'm concerned, you are just lucky to not have many cheaters and perhaps your trust factor isn't as high as you think it is.
