His 'complete' tweaking service is an empty scam. He promises an entire overhaul of your xrumer files and configurations, less than 10 files are different from default and those are f*king stolen rehashed bullshit! There are many people he has scammed but he always seems to get away with it because he moves paypal accounts quite often. Avoid this lowlife. EDIT: OK THEN Bryanon What I ordered: a full overhaul / 'next generation' modification to xrumer 7, with increases in success rate promised, 'hundreds' of heavily modified files What I got: All default xrumer 7 files, except 8 files (a far cry from 'hundreds'). He's actually advertising xurl and xmessages as his own, when they are botmaster's, and has stolen and rehashed the files that were modified, i.e. none of it is his work. Success rates are actually WORSE than on default (no XAS_AI) and xrumer often crashes. I had to delete all his files. His response: "You are a moron." You can read the rest over at VIP BST on ******.
