Since Xrumer spams forums really, how can you expect backlinks from the posts? Don't admin delete the post and ban the account? It sounds to me that you post an ad on random forums that is 100% self-promo. This is exactly type of posts that are deleted, especially staffed with keywords and URLs in the body of the post. Plus don't you expect your site get spam reports? And for those who use it: - does it bring you targeted traffic? - how many backlinks you can build in 30 days without Google get suspicious? - how do you setup your host server to email all that (in the video demo of Xrumer the guy uses his own server for this reason - anti-spam issues).
