The same thing happened to me. I don't know this person, and when I went to their profile I had been blocked. And they never commented on anything I wrote either. So what. His loss. Lol
You may have asked a question, or given an answer to someone else which put their knickers in a twist. Who knows?
The question may have been withdrawn.
I think theres certain questions that can only be answered by people in certain groups now. i vaguely recall something of the sort. if it has a group name under it that may be the issue. think its a fairly recent change coz most in q and a like to clown around so if its for a specific group they have an option like this i believe. I havent experienced this personally but i seem to recall seeing something along those lines
could also be a random EP software glitch ive had that one myself. later i could.
The questions might be flagged or something. If you click on their profile you'll know if you're blocked. I'm always completely blown away by the people who block me lol.
Is it the first time ?
Are You blocked or flagged ???
Are You able to watch his/her profile ???
Oooops... Don't have immediate solution.
May be ask to a common friend of Yours what is it happend ?
