I never use proxies for harvesting, I've done lot's of harvesting and so far google has asked me to type in captcha like 3 or 4 times total when doing a search. It's temporary after some short period google seems to delete this information because everything is back to normal.
If you really want to avoid akismet and other wordpress anti-spam tools sure go ahead and use proxies. In my oppinion proxies are of no use if you don't intend to do pinging to increase counts.
I tend to focus more on making sure comment is unique, I post 1 comment for each domain, and email and name is different everytime I try to post.
I don't understand why everyone is so worried about proxies.
