I have no idea how i stumbled on this thread but i read through it and just had to give my two cents to this. Yes spineless MC's are a plague of this game genre. They ruin the whole story because they act and decide how no one would in real life in that situation. They get dragged into bad situation that can have been avoided if they had even the slightest bit of self respect. Its annoying and takes you out of the story. Best example i can give is the MC from "My new Life" or "Power Vacuum".
But i have to disagree on the pervert MC's. They are a necessary evil. I enjoy a slow burn but sometimes i just want to fap, excuse my french. A stoic or empathetic MC or MC's that are heroic or whatever wouldn't fuck a girl 2h after they met. They wouldn't go after 10 girls at once either. And if they do, like in BaD, they get punished for it later in the story.
Sometimes you just want to sit back and enjoy yourself without following a walkthrough on how to not piss of the Love Interest. Because usually you cant do anything wrong it the pervert MC games.
Now to answer the original question, i can name 3 people.
Grandpa from "Power Vacuum", Christian from "My New Life", and fucking Waldo from "What a Legend"...fuck that guy.
As for girls: any girl that walks over the MC like they are worth nothing. Usually these characters are paired with the spineless MC's and that makes it so much worse. Sometimes both MC and the Girl redeem themself it the future. But most of the time the damage is done.
