So what? I don't really have the same opinion as Sargon either, but he is a prominent content creator. Why wouldn't he be allowed to have an account on Steem?
I know you said you'd rather not have him around, but in the end everyone can create an account here and that's the beauty of Steem.
Heck, if Anita Sarkeesian wants to create an account here, I'm not going to try and stop her either :P
