Different ways to block someone on Facebook?

[Don]

Hey. What are all the different ways to block someone? The only way I know is to actual do the blocking inside their profile. Actually I found out there is more then one way? Or unless Facebook updated the blocking? While going into the profile to block someone that would leave it where to write a message is not visible and then that's it. I think someone has blocked me but with the way they did it this time is you could write a message to them, but it will come up as invalid receipts. So, exactly what blocking method is that? Like I said the only way I know would be just block them in the profile and then that will cut off the message part.
