What does it mean if you can't see someone on your facebook and on someone esles you can?

Does that mean that they blocked you? There photo is blank and i cant click on there profile, but on my friends i can see it fine.
I do that all the time and still, nothing..
I cant even search for that person. :/

Delete your history and cookies on your browser and then log into FB again and see if you can see your friend.

i think u shouldn't worry to much about this.
Facebook glitches a lot or something because one day I can click on a friends picture the next day it won't let me.
If this isn't the same glitch then maybe they have it only for certain people to see it, so they feel comfortable. Maybe your over thinking it and they didn't block u, especially if u don't know them too well, but if u do and aren't on great terms with the person then maybe they did.
