If you're feeding XRumer, it's wise to use Hrefer as they excel at forum profiles and have more success. If you're using GSA SER for profiles, make sure to check deep analysis engines or check all engines. GSA engines depend on certain platforms, and platforms like MyBB, BB, and vBulletin specifically need them. This is why GSA SER doesn't remove duplicates at the file basis. GSA SER works with dependent engines, and the same target accepts multiple engines, and success depends on it.
You don't have any updates on the given platforms; open your browser and browser console, match the .inis, and you'll see all tokens are the same, and those CMS platforms don't change often like Web 2.0s. After all, those are static registrations. You should learn more before making a statement.
If you don't know how to scrape and use the tool, just grab a good link list and try it. I use XEvil with the latest Google updates rather than XRumer. GSA and Ranker X combined are great compared to XRumer, in my opinion, because GSA offers more diversity than any other software.
Botmaster and GSA are both great companies and come with different properties, so it's stupid to compare them. From the GSA company, the best tool they ever built is GSA SER; it was their turning point, while Botmaster's XEvil is noteworthy. GSA's website content form submission, on the other hand, is a big fail, and so is their content generator. For generators, SEO Content Machine is the best. I agree, SERLib is a joke because it limits GSA SER capabilities and is not worth the price.
