I have suggested in comments that the user tell us why he should not be considered a spammer. Today he replied:
@John Saunders: It is obvious that WebDAV and FTP are related technologies. If you need an explanation why "WebDAV is much more modern and feature-rich" here is it: stackoverflow.com/questions/3714363/webdav-vs-ftp-sftp-ftps – user424257
I do not consider this to be an adequate defense. What does everyone else think?
