     I thought his question was very clear.

     He stated that a VPS company (I've quoted his statement above yours,
so please go back ad read it again) complained that the attacks were
emanating *from his tor exit*.  The VPS company is very unlikely to be
moved by your suggestions.
    The second matter that was clear was that he has been running a tor
relay without having read the documentation.  If he wants to restrict what
exits from his node, then he needs to read about exit policies in
particular, but he also ought to read the rest of the documentation as well.
     More generally, people really should not be running an exit in
ignorance.  The tor project has done a commendable job of providing a well
documented product.  The documentation was intended to be read, not ignored,
by those wishing to run tor, whether as a client only or as a relay.
