What are some of the exploits that you guys remember from back in the day?

I discovered one myself, as far as I know I was the only one to figure it out.

If you targetted an npc, any npc, and typed 'dono', up until mid-Velious, the NPC would stop, turn to face you, and not move for about 2 minutes.

This worked on the boats, too.

Teenage me had a lot of fun griefing people on the boats by stopping it randomly in the middle of the ocean. All you had to do was walk down to the belly and type 'dono'.

They patched it out a few weeks later, never got in trouble for it or heard from a GM or anything.
