Its one of 2 things for me....answering the same question over and over again when (like sunni mentioned) that was just asked 8 min ago in the same thread , or opening "pandoras box" by answering a simple question with a noob that then finds it necessary to ask you every question known to man regarding "what about my grow,lights,veg period,medium,room size,temps,humidity,seed stock",etc that they know nothing about instead of reading up on something (before they start the grow-not after).
I'm always down to help someone but I usually go into dickhead mode when someone asks a noob question "please help me", then argues with your honest reply or when one bitches when they aren't getting an answer in 5 minutes. In the time it took them to bitch in their thread about not getting answers, they could have read an entire book on the subject lol
