When pvping, activate the following macros.
1)
Name: Trade
/trade;
/pause .00001;
/macro trade
2)
Name: Duel
/duel;
/end;
/macro Duel
This works great on people who have older computers. Me and a buddy tested this, along with all the other macros I submitted and we found that if the enemy is moving around alot and you are spamming them with this, it makes it very hard to see, chat log is un readable, and even causes them to lag.
This way you can cause them to lag and spam them with system messages. Since this is not a /tell or a spatial chat, it can't really get you into trouble because since when has dueling and trading been against the rules and when has a CSR ever done anything?
