Anonimity with blackhat domains?

So I'm thinking of setting up a niche domain through Blogger or Wordpress - after this is set up i plan to use some blackhat SEO methods on this domain to get stuff rolling.

My question is: how important is total anonimity when doing this?
For example, is it OK to use a blogger account connected to my main e-mail address? Should I use proxies while setting up this domain?

I've seen one thread in which someone was suggesting creating multiple fabricated identities when handling different blackhat operations.

Your views?

first of all , don't use the blogger account that's connected to your mail email. Just set up a new hotmail or something and use that with blogger. For blackhat SEO anonymity ain't that important , but you don't want to fuck up your main blogger account for stuff like this.

Most ppl that use fake identities and anonymous domains and whatnot are mostly running some serious blackhat stuff ( like border legal stuff )
