The reason for it works better without proxies is that the connection is much faster, and don't have to go out and connect to the proxy first and then load the page, many times the proxies are slow them self to.
I don't know exactly why it's a problem to post without proxies, but if you hit 500 or 1000 or 10.000 blogs in 30min I could imagine that maybe something like aksimet would detect the ip and block it, I don't know if it could detect it, but I don't feel safe not using proxies when hitting over 100.
You could also risk if many blog owners complain to your website host or domain name account that they will close your account, but then again the proxies don't protect against that, as they can get that info from your website link by going to whois or places like that, you could make your domains private but that should not be good for rankings. So that's why it's good to use sites like squidoo, blogger, weebly and many more (feeder/buffer sites), and then make the links go to them and from there to your own site. I guess you don't get all the "juice" out of the links that way, but definitely better than losing the site.
If the comments are written and spunned good and fit in with the category of the blog, you use many different emails and some variations of your keyword/s maybe mix in a couple of names "you should always do all this", I guess it would be ok to use your own ip. But I would still be a little worried if I did it on thousands of blogs, you never know.
It can be hard to find blogs in the same category, when I for an example searched for guitar blogs, over half of them (out of 5.000) was not about guitar. Of course, the more you harvest the more unrelated results you would start to get, so if you set it to 100 results per keyword and make it "phrase match" it should be pretty related. You could also just search for blogs with a related keyword in the url, that would help a lot I think, or filter them without the keyword in the url out afterwards, that was what I did with the guitar blogs.
It can also be done by searching for a celebrity a known TV show or something like that, and then write a comment around that. It is when the comment is totally unrelated that people most times won't publish the comment.
I had my slow poster on 35 seconds timeout on the last run (remember I use free proxies, private proxies are much faster), but I'm thinking about 30 next time, course it seems like if they load more than 25 - 30 secs they never go through anyway. But it would also depend on how fast the proxies are.
