Nobody but staff will know that answer for certain. I, however, and certain (without being able to prove it) that that is the case.
Also, when you don't even take the time to upload a profile picture, it becomes pretty certain that you are a spam artist, and people will be flagging your profile and hubs as spam. I've never actually flagged anything on this site, but I've thought about it a few times, and I've see two diff no pic profiles with the same spam content here before. Spam style content brings everyone who is serious here down; and so we all need to pitch in to keep it out of and off this website. My five cents there. . . .
