Mmm... I think I have blocked just one user in my entire existence in FA (counting all my previous accounts) xD

The "one who blocked ya" at least should have to give you a reason =/

I had this happen a lot honestly, but mostly because of one Drama queen pulling a mass amount of people into a hissy fit and pretty much bad mouthing me. = w= gotta love FA.

I think we have all suffered this at some point.
Experience ( From both me and my friends, and apparently Kitsune up here^ ) tells me that 90% of the times when this happens out of the blue and without provocation, it happens because there´s a common "friend" who happens to be closer to them than you are, and badmouthed you.

I don't think that's ever happened to me O_o

It happens, people have their own reasons for how and why they want to control their web interactions. I've done it to others, too, and have my own personally informed reasons for it. There's not much that can be done about it, and generally trying to get in contact with the person indirectly to find out what's going on will only make things worse.

Soo they blocked you for something and didnt even bother to tell you. Thats just odd

I've been blocked by some guy who apparently thinks i've caused drama, that's the only reason he has for blocking me at least.
Thin skinned, is what i consider him.

That's weird >.>
