I know it has been a while, but I'm just seeing this. I went to look, and I can see that Swissclive is still trying to flag the guy to make him stop. A report was submitted to:

https://steemcleaners.org/abuse-report/

They know about the guy now, and hopefully he'll get squashed soon for the abuse. Thanks to you guys for bringing it up here, or I would never have known it was a problem!
