Hi,
yes, the data may be of a legitimate business, but these entries are made by some SEO company they hired. There are about ~ 10 of these nodes each day, across the world, all with the same tagging, same spelling mistakes. Creating new user accounts for this without stating their SEO identity is clearly in violation of the OSM rules. 

If it were mistakes by innocent users, I'd be happy to correct them - but these nodes are clear cases of misuse of OSM.
