Well my own experience shows pretty much what Linkster is saying - google rarely lists a standard freesite anywhere near high enough in SERPS to worry to much, yahoo on the other hand seems to like freesites a lot more, and all the pages within it. A standard freesite that I build for LLs I also build for yahoo.
I'm talking about changing 1 page per freesite, the warning page. If your version for SES that you list on your own hub has links to toplists, backlinks from toplists, different text geared towards different keywords etc. etc. then imho it's a completely different page and wouldn't be penalised for anything.
And listen to Linkster, he knows his stuff
