To that, I went to the old hidden service url, and looked at what kind of ads was presented[1]. Did I see any spyware? No. Did I see any scamware? No. Any toolbars? No.
What I did find was sex ads of plenty. That makes sense. What other businesses would risk being accessory to copyright infringement, but an industry that often need to hide themselve (unjustly, but that's an other story)? An obvious observation from the trial is that any kind of trading with the TPB, be that bandwidth, hosting environment, electricity or anything whatsoever can be enough to land you in jail for accessory charges.
Conclusion. benologist comment was FUD, likely influenced by his own revenue source. However, if he provide a source for his statement, I am fully willing to change my opinion.
