You're right, there's a whole world of options that would be

Thalium poisoning
Submarine launched cruise missile
Dropping in an active volcano
Steam roller
High voltage
snakes

Feel free to add to the list, everyone

Hmmmm....with apologies to Paul Simon:

The problem is all across the net, he said to me
From alt.pix.puppies to rec.auto.datsun.z
I'd like to help you try to stop his awful tune
There must be fifty ways to whack a net-loon
....fifty ways to whack a net-loon.

I know you don't want to be violent or be crude
Even when the idiot net-loon picks a fight or just is being lewd
Or posts a JPEG of his pimple-studded moon,
There must be fifty ways to whack a net loon
....fifty ways to whack a net-loon

Just toast him like bread, Fred. Make it a jewel, Euell.
No need to be soft, Croft... just listen to me.
Make the idiot scream, Gene. Send his blood pressure up, Chuck
Just question his life, Dwight, it's a fake I.D.

He said it grieved him so, to see that tired old game
With the net-loon twisting all the quotes but misspelling his own name
Remember that when he posts, he's probably dressed-up like a dame
There must be fifty ways to whack a net-loon.
....fifty ways to whack a net loon

Just sign him up for spam, Dan. Killfile the snake, Jake.
Don't do anything small, Paul...really nail that S.O.B.
Give his ego a bruise, Bruce. Point out he's a jerk, Burke.
Just flame him online, Ryan...and get yourself free...
