Should I bother renewing my domain now im banned?

2 sites banned from Google

[crimsonblack]

last month 2 sites dropped off the index.. they can still be found in yahoo and 1 page in msn.. but thats it. they have no page rank.. where they used to have page rank 5

so is it worth renewing ot just let them expire?
thank

If they are ranking in other engines, why on earth would you let them expire?

[crimsonblack]

well if i have no page rank... does that effect my ranking in yahoo?

[pmac]

No, page rank [webmasterworld.com] is a method that Google uses to score pages and has nothing to do with Yahoo. You did say your sites are ranking in Y! and msn right?

I rarely will let a domain expire, you never know when its going to come back from the dead.

Often, traffic from past link campaigns can cover domains and hosting, even if the links no longer contribute to any search engine rankings.
