Earlier quoted context omitted.
This doesn't work in Germany, for example. If you charge back, they'll just put you into a central register (called Schufa) that will basically make it impossible for you to get a credit or even to rent an apartment.
It's not a charge back in that sense when you report fraud or card theft. And I suppose that the effect you describe results from abusive requests from charge backs. I doubt you will be refused a mortgaged because you were a victim of theft in the past...
Don't be so certain about this. The credit reporting agencies are evil, nasty blackboxes and it is not transparent how your score is influenced, even by fraudulent stuff.
