I do not think he said you cannot post links to threads, or even certain posts which is done quite often and can be helpful as informative, but that we are not to post links to continue a debate from another thread, but to go back and deal with it there.
That is hard not to do when dealing with a poster who uses the same tactics from thread to thread which you object to as it degrades the level of debate, but they deny it, or denies he/she said something contrary to what they now assert, but i think the intent is to stop crossover personal debates.
