So, you are a "cool" guy, talking with a cool chick.. and suddenly she went to offline.
there can be three things..
1.She just changed presence
2.She is really offline
3.She blocked you.
Instead of asking stupidly like "Am i blocked?" do this.
and send it. It wouldn't even create a blank window!
If you get the message "/t is not a valid emote command" then she is online.
but might have blocked you
If you get "the username is not online", then you know.. she is really offline.
Now, you want to check if she blocked you?
if you get "the user is not online" then awww... she dumped you!
