Less so with time, but at first I was.
Most Bitcoiners know me only as Brisket.
I've found that the further you travel, the less risky it becomes. The more PoW to get there, the less likely scammers will show up.
In time as this thing becomes more popular, I imagine that I'll reduce the number of new unknown nodes that I'll accept connections with.
Most scammers/theives play a numbers game & I live pretty remotely. You've gotta have some balls & knowledge to come up my long driveway uninvited.
