link between my black sites

i read that Its good to make the the structure of links between my black sites like this:
domain E link to
domain D that link to
doamin C that link to
domain B that link to
domain A
and so on...

and never close the circle.
that what i read.
what do you think about this method?

Never make it look like your black sites have engaged in a link exchange, and you should be ok.
