(Ahem, I am the OP... :) )
Yeah I have definitely seen it from more accounts! Only a couple of the accounts I've seen that behavior from, said that they had been hacked. I remember one guy even had to create a different account since they changed his keys, but he did eventually get his account back. Don't recall who, but it was one of the "bigger folks" on here -- not sure if that meant wallet, or rep, as it was in my earlier days here.
I'm happy with what I did, too. :)
wow!. That's a serious one. Learning security above anything else is crucial in this space.
