So far so good for me with the gremlin bot.

I started using it yesterday, got me 2 bags full of Saronite and got my rogue from 46 to 50 lvl.

Today while botting , there was a player who was following me. The bot alarm went off , i stopped the bot and i started playing my toon. we eventually dueled afterwards:P . What i don't get is, why follow someone who you think is botting? What can you discover by doing that?
