Xrumer 7 uses automated captcha servicing... however, it does seem like people using blog comment Xrumer mods (drupal X mods etc) and doing guestbook/link posting areas have taken over a lot of very high value terms since penguin.
Dude are you seriously telling me that Xrumer has auto captcha solving? Thanks for letting me know, I was wondering what that "Automatic captcha solving" option was in speed and success rate tab. Lol. Of course everyone knows XR has some OCR capability however if you have used XR at all you will know that it a) has relatively low success rate at solving captchas, especially the most common recaptcha and DLE, which are changing ALL of the time especially since Google now owns recaptcha and makes it an absolute BITCH - by the time botmaster cracks it Google just change it / add a new twist e.g. blobs, street signs, other ridiculous shit; and b) XR's OCR can only solve a limited number of captchas, mostly restricted to FORUM captchas since it is after all primarily a forum spammer. There are a few guestbook captchas in there as well, mostly relatively simple numerical captchas, and newly phoca gb has been added, but if you want to hit guestbooks, you will still need external services.
Basically, for any other modifications outside forums, you will need to use external captcha services if you want any sort of success. I can tell you that the drupal X mod is a steaming pile of shit and pretty much does nothing. There is a reason why things like that are released to the public and that is because it is shit, it came from xr ch@ after all. Similar to the phpld mod which actually doesn't work at all for various reasons. Those who are spamming platforms outside of forums are generally either modding xr or making their own custom bots.
I still think OP should look at other ways of making money than SEO. In the future I think backlinks will be phased out or at least devalued greatly, and backlinking in a certain way can have adverse impact on your sites now. Even doing shit by the book can have you hit so it's a lottery. It's not a viable business plan to include SEO with G at the moment.
My view is actually that XR spam, even spam in general not just XR, yes via guestbooks, blogs, wikis, forums or whatever it may be, has taken a large hit and is significantly less potent than before.
