What is XRumer tool and how to use it?

Xrumer is an automated link building tool created by Botmasterlabs in 2011. It was originally promoted as a tool that could build massive amounts of forum profile links in a very short time. Think of it like creating hundreds and thousands of backlinks to your website within a day.

XRumer is a piece of software made for spamming online forums and comment sections. The program is able to bypass security techniques commonly used by many forums and blogs to deter automated spam, such as account registration, client detection, many forms of CAPTCHAs, and e-mail activation before posting.

It is an automated link-building tool and I would like to suggest @op to avoid the use of it as it will lead to facing a penalty to your site by Google.

I agree with @ritesh!!
