I heard that. I even heard it for things I'd never had thought could be 
related, such as cdrecord and cdparanoia (it seem that braille displays 
just work with \n so the updating tricks with just \r were a problem).

dunno, there are lots of web sites (and I think some regulation in EU 
and USA) that basically is "non text stuff should have a text 
reprsentation", but given a text representation even automated things 
can parse that (except if it requires some non obvious logic).

But as Jim Weirich reported it seem that most automated attackas were 
stopped, and actually it seem that no spam happened on rubygarden today.
