Well, Fyaconiello, let's say Ichigo hasn't performed a single Konso after shattered shaft, though I think we simply haven't seen him perform any, as they were not important to the plot. When Ichigo recieves a Hollow alert through his combat badge, his activities should be monitored by the S.R.D.I., and I'm sure they are able to tell whether a Hollow has been purified and sent to Soul Society, or if it's existance has been completely erased.

Considering that, if Ichigo has been destroying Souls all this time, then the S.R.D.I., or Mayuri in particular, has been hiding this fact from other Shinigami for some reason. It would certainly create an interresting plot twist, as you mentioned, but I find it rather far-fetched.
