--- Comment #1 from John Mark Vandenberg jayvdb@gmail.com --- Is the backtrace in this example modified? i.e. 'private' words replaced?
With the current code, I can log into ar:wikipedia and edit on Linux using 'JVbot' which should be functionally identical to the ascii 'UserBot'.

I will continue investigating.
