So I experienced something new today, and thought I would share for those poor souls who may experience it in the future. /busy is your friend.
I was on my relic quest to kill x number of a few different types of mobs. Saspa Spawning Point mobs or something. Anyhow, when I arrived the area was pretty empty, though many of the mobs were dead; you could tell someone had been there recently. I took to killing the NPCs in the only camp where I could see they spawned.
Eventually these 2 whms come along and start AOEing EVERYTHING (I only only been there about 2-3 minutes at this point). I immediately asked if they wanted to group up, and one replied "after you leave sure". I said alright and warned them that I would be there for a little bit. They polished off the last of the mobs I needed and back they went to wherever they came from.
So this time I got smart- hopped into the middle of the camp and pew pewed away. The number of mobs I needed started to tick down, when suddenly they arrived again. This time, one ran right up to me and opened trade. Odd... I closed it. I began casting a spell again... trade. 0_o Spell... trade. Spell... trade. I couldn't cast. I couldn't heal. I really couldn't do much of anything except die, and die I did. In hindsight, of course, there are a few things I could have done to live, but I was so shocked at what was happening that I just sort of fell over.
Luckily, I have a supportive guild who suggested using /busy to put a stop to that. So I return to the spot to get the last 5-6 mobs I need, and here they return. Immediately a trade window opens, and immediately I type /busy. They stood there for a second, obviously stumped on what to do next, and then say "lol /busy! Only botters use /busy! Reported for botting! 2 times!" (since there are 2 of them) and ran off.
I soon after got the mobs I needed and went on my way. I put in a ticket, reporting them for harassment.
Remember folks- if someone trade windows you to death, use /busy to save yourself!
