Do you mean on Twitter? Certainly ones he has blocked have just re-registered with a new alias. They say so.
If you want to see what Eric tweets and he has blocked you, you can just not log on in to your account that he blocked and view his tweets, then reply to what he said on your new alias.
I am blocked. I just read what he tweets not logged in on one browser and then reply logged in on another browser to reply tweet someone else made.
