I implemented a single, trivial response for register requests according to:
http://metajack.im/2008/08/28/writing-ejabberd-modules-presence-storms/

To build, simply put the erl in ejabberds src/ directory and run

    ./configure && make

Then put the mod_register_refer.beam to /usr/lib/ejabberd/ebin/ and add the
this to the ejabberd config file:

{mod_register_refer, [ {url,["https://accounts.spline.de"]} ]},

mod_register itself should be disabled, I did not test the coexistance of both modules.
