I've got a facebook question?

[epicdorgon]

I saw this comment on a post the other day...

And it was a bunch of keys/letters, going up the comment boxes through other peoples comments.

Sorry for the terrible description, if you know how to do this, tell me, and I'll gladly give you best answer.

it may be the list of people you have tagged in and you might have unknowing put your mouse cursor over the link and the list have shown up hidding other people's comment
or the person might have done some trick with the facebook comment box and done what you are seeing
