I think you've just missed this what I said.
It seems like you really are helping your friends too much, by what? Trading Merits?
And also
I have only this account but these are my friends and we are working together on the forum,
Working together huh? Yeah, your Merit transaction with your friends proves that you really are a good friend. Also proves that you abused it.
Why don't you ask for your friends for help to remove your Negative Trust instead. Looks like you're the only one looking for solution. Are they just friends for benefits?
Oops. Sorry

Edit. One more thing. Did you even know that I also hate Merit Abusers?
