[Victor][1] seems to keep posting links to Groupdocs.com on every question even remotely related to PDFs or document management. Some recent examples:  

 - http://superuser.com/questions/43321/document-management-system/413122#413122
 - http://superuser.com/questions/41268/how-to-create-a-simple-document-assembly-application-for-word-documents/413116#413116
 - http://superuser.com/questions/298122/opening-doc-files-as-docx/413113#413113

According to [this website][2] he (or at least someone with the exact same name) is working for GroupDocs, which would make his posts plain self-promotion. Can someone look into it and deal with him?
