Wanna make sure this is correct.

I have everything setup for Xrumer although, I have a scraped list from Hrefer and I am not sure if it is wise to just plug that into Xrumer without any sort of Filtering. I heard that you can misconfigure Xrumer to spam a single site.

Thread moved to Black Hat SEO Tools section.

Don’t run raw Hrefer lists straight into Xrumer unless you like burning resources. At minimum, filter by platform and remove dupes. I usually run a quick live check + sort by OBL to avoid nuking trash.
