If you have blocked them, then you can't see them and they can't see you.

You won't be able to log in and plus no one can see your suite or your username.
You can't. You will know if they BLOCKED you when their status becomes offline with an "?". If they only deleted you you will still see their online status.

The best way would probably be to ask a friend (or multiple friends) to put this person on their buddy list, and if they see the person online, let you know. When they do, you can see if they appear on your buddy list. If so, they have not blocked you. If their name is not there, then they have blocked you. You can also do this yourself by creating a new screen name, adding the person to your new buddy list, and linking your two screen names (edit>settings>buddy list>linked screen names) so they are both online at once. Note that this will only work if the person does not have settings where only his or her friends can see the screen name's online status. You can also use > http://www.buddycheckscript.com/index.php to see if they are online. This will tell you when they are online, mobile, or offline. If they are online or mobile, and you don't see them in your buddy box, then you more than likely Blocked.
Are you asking: How to find out when you are blocked on twitter? If so here is what I've found so far. One twitter subject I've found reports: "At first tweets were unable to be seen and I could not login." If this accures, then chances are that you've been blocked. Also more info can been found on the subject if you go to: "Ask Dave Taylor," or Type in on search: "How Do I Block Someone In Twitter." This may help answer your question more clearer.
No . he would be unable to know that you have block him.
You can go to www.blockyell.com and see who blocked you.
You can watch the video about the boy who blocked his own shot online at the YouTube website. You can also find this video online at other websites such as Last.fm.
If they blocked you you cannot see their profile. The only way you can see someone's profile is if your their friend on Facebook.
The person either has you blocked, has deleted his account, or does not a profile picture on the Whats app if you can't see a picture.
