Scrapebox manual poster (question to loopline)

Hello everyone, and especially @loopline, i hope you will read this.
I am thinking of trying to start posting comments with Scrapebox manual poster. I looked some information about it, and suddenly found a post from loopline at scrapeboxforum in 2017 (i can't post link now, because of lack posts here), he says: "The manual poster was great back in they day, but its usefulness is out lived. In fact they almost removed it along time ago, but just have not yet."
So i have a question, what is wrong with manual poster in scrapebox right now?

Yeah, if you mail the support they will say the same. The issue is its limited to using IE rendering engine.

Internet Explorer (IE) is a problem in and of its self. Plus it can only use ip authenticated proxies. User/pass based proxies wont' work.

Another point is that the types of things you might want to comment on now manually are not the types of things that can be auto filled by scrapebox anyway, at least not without training. So essentially all you are gaining by using manual poster is auto rotation of proxies and working thru a list of urls.

You can easily find a proxy rotator addon for firefox/chrome etc... Also you can find addons that let you load a list and work thru them.

At that point your using the latest browser tech and addons that accomplish the same things as scrapebox can do and your not limited by IE. Further you could get an auto form filler addon and be ahead.

So basically the manual poster was great in 2009, 2010 etc... but the premise on which it was built is no longer valid. so everythign else in scrapebox is still useful and relevant, but this one feature has out lived its usefulness, in my humble opinion. at least as a manual blog commenter.

The reason its still in scrapebox is probably because some person or few people have some creative uses for it that are non standard and so scrapebox support wants them to be able to keep doing whatever it is that their doing. My guess anyway.

Ok, i see. Thanks for the detailed answer.
You said there is auto filler addons, list loaders and proxy rotators for browsers, can you tell what addons are these?

I dont' have a specific list, if you google for them you can find the reviews. There is more for Chrome then there are for firefox though.
