This is a file I put together a year or two ago...
It contains all of the XRumer footprints (which HRefer searches for) and each is in its own individual text file ready for Scrapebox.
For example, for vBulletin, the text file reads:
(which of course searches for the keyword and vbulletin in the URL, the title and in general.)
There is also a "XRumer FP" text file which contains the original XRumer footprints.
This took a long time to put together, so if you're a XRumer user and want to scrape your own lists.. This bit comes in handy.
Simply extract it to a folder and in Scrapebox, click Merge Footprints ("M") and then type the keywords.
