IP Cloaker / not having your actions tracked
In an industry where you can pretty much get some relative success by copying what other do, do many use IP cloakers of some software that complete covers up your actions on the internet?
I just had this thought that if someone knew exactly what steps you were taking they could pretty much jump into the same niche and try and do the same.
Is this usually the case? or do many here actually cover up all their tracks?
I've also read (can't remember where) that such software might affect search engine rankings.
Really, is it necessary to take security to such lengths? my assupmtion is YES but i would like your oppinions on this.
