What a curious block. I restored the original sources about those figures because somebody recently replaced them with sources that do not even talk about those figures. And I included the source about the 3 million Portuguese in São Paulo, because the user "Ninguém" included a "fact tag" there. Curiously, the user "Ninguém" reverted the original sources I included. Then, he's the one who started the edit-warring.

Isn't "vandalism" to reverte an user that replaced a "fact tag" with a source and restored the original sources that have been there since a long time, but somebody replaced them? I gave the source about the Portuguese, and "Ninguém" replace the source once again with a "fact tag" and he also reverted to the "new" sources which are from a not reliable site, including the one about the Portuguese which do not even talk about the figure. 

I included the source which does talk about 3 million Portuguese and it was reverted by "Ninguém" without any explaination. Isn't vandalism to erase a source and replace it with a "fact tag"? If this is not vandalism, if it's a normal edit to erase sources and replace them with fact tags, please tell me.
