The issue mentioned of reusing nodes doesn't seem like much of a concern considering how the onion routing works (even if the routes are all the same nodes).
this is interesting to ponder on, it is clearly over my head because I am not sure why this would cause an issue, even if they reused some of the same nodes. in theory if anything could be gained with tor over tor why would that same information not be attainable in a single tor instance? why is information considered exposed if any node is reused?

But the performance alone is probably terrible.
