I suddently regretted Google was not able to distinguish that all the articles were the same, and hidding other articles which are unique, but simply less visible. I actually wonder if this is not a bit problematic. It looks as if the search system was not able to handle this properly any more.
It seems this is solvable though, if Google could simply read the attribution links. Of course in this particular case it wouldn't work, because biography.ms has scraped them off, but in general it should world well.
I'll write them.
