Test response. Came in to edit. I think I understand what you are saying. I don't stay logged on all the time, I log in, log off.
I haven't read much about it and won't, I have too many bugs of my own. and just type in word and then paste it.
I am certain it has kept a few from posting though, because they don't type too well and a couple paragraphs is a real effort for them.
If they are then timed out, that's a lot of effort down the drain for them and they don't try again after the second or third failure.
