no, I have never plonked anyone, at least that I can remember.
I think I did once, for a day, but changed my mind.
Even if they're the dumbest ass-hat there is, it's just as easy to ignore what they post.
But, I've seen even people with names that are just letters and/or numbers, post some interesting stuff.
For me, it'd be almost cowardly, to plonk someone.
I don't imply, it is cowardly of anyone else to do so. I just don't feel threatened or whatever, by anyone.
And I get greater pleasure (If only in my little mind) of posting around someone, just to ignore them.
Now, I know I have been, and am plonked.
Well, if they can't address me directly, to make sure it's not a mis-understanding..........foogem'
and, the horse they rode in on.
