I really don't see how a simple /tell, that does not need any response, is annoying or can stop you from playing the game.;
I can understand someone being constantly spammed with RMT tells or any tells to be annoying or hinder his gameplay. And if I remember correctly, Hikuzo when I was on Cerberus you were more annoying then the RMT tells that I got, which at most were at least 1 every 3 hours and my name starts with a G.
