Xrumer Strategy - Is this Effective?

I outsource my xrumer blast to a guy in BHW. He blast a lot of sites/pages with xrumer in one go, around 30 links in 1 post.

It has been 16 days since I ordered xrumer blast from him and I can see my sites are gaining new backlinks through backlinkwatch.com , some of my sites have now 3000+ backlinks after only 16 days, prior the blast, they only have 100+ links.

However serps for these sites remain unchanged in Google. No Google dance or slap but no increase in serp rank as well.

Is this normal?Is this strategy of blasting 30 links in 1 post works?How well? All the blast wnet directly to my money sites.

Comments please.

Thx

30 links on one post? seriously? I hope you don't expect those to stay around very long. Any that aren't on worthlessly spammed forums will probably be removed. The goal is to try to look natural and 30 links in one post is NOT natural.

He post it mostly on abandoned forums so most of the links stick.

they stick, but abandoned forums have crap for PR and are usually spammed to hell so they're there but they're virtually worthless. You need to find the balance between quantity and quality. But having 3000 links from known junk forums is not as valuable as having 300 links from high PR, high quality forums.

Well if he blasted enough forums the 30 urls willl get some benefit. Are the 30 urls different websites, or are they all from the same website?

15 different websites , each with two anchor text variations
