Is there a way to prevent people from blocking me on facebook?

[Drizzy]

I'm really tired of being blocked on facebook, and sometimes I get blocked for NO reason! This kid is telling me he can do this for me, but I have to give him my password, but I'm not going to. He got mad, because he wanted to help, but I don't really trust him. I tried blocking one dude on facebook every time I hit ok it gives me an error message, it wasn't a glitch, because I blocked another person, and it blocked him! Is there an app on facebook that prevents people blocking me? I'm blocked by 20 people! Please answer and I need really good answers! Also I want to be unblocked by those people, NOT because I want stalk them! Please answer! If any hackers see this answer!
I tried canceling my friend request. It kept saying friend request sent.
I'm not being obnoxious with people. I just message people in a normal way, and I don't creep on people's wall, or update my status every 5 seconds

No. It's THEIR choice not yours. The thought ever occur to you that there must be a reason for it? Personally, I'd block you too just from reading your question.

There is no way to prevent people from blocking you.
It is a safety measure set in place so that people can protect their facebook.
There is also no way of knowing who has blocked you, so I'm not sure how you managed to figure up 20.
If there is an issue with it not letting you block him, just unfriend him and don't pay attention to him if he sends you a message.
If you want to be unblocked, talk to those people (if you know them in real life), otherwise make a new account and try getting them to add you again.
They may have blocked you because you post too much or spam their feeds with useless, annoying crap like videos, lyrics, game invites/notifications, etc.
And that boy asking for your password is not trustworthy. Never tell anyone your password.
