I don't understand why this was done to me, how is this community?
Gave me the red tag, thank you guys, you are very good, I wanted to help the beginners in the beginner section, but some people did not digest it, Today my heart is broken,

Your general posting style seems ok, I can’t speak for marlboroza though. You’ll have to take it up with him. Message him privately or something!

I'm assuming those instances of "partial plagiarism" were reported?

Negative trust probably isn't warranted

The negative trust this guy got was superfluous, because plagiarists generally get banished, and there will be no need or way to get that feedback removed once the moderators look into this.  It's a non-issue IMO.
