There are some threads you probably have seen as well, that just make you want to slap someone. This happens frequently in beginners & help as well as other subboards:

OP What is X?
#1 X is ... (short answer)
#2 X is, because. But you could also understand it like this or that. (long exausting answer)
#3(OP) wow thank you both, now I understand X
#4 X is... (redundant answer, sometimes even bad)
#5 X is...
#6 X is...

this gets worse when the thread hits page 2. You get the feeling that those answering #4,#5,#6 etc. did not read anything but the question. Sometimes they do not even answer the question but post something that is within the general vicinity of the area of the topic. Is that spam? To me it is, its the worst kind of spam. It bumbs a thread that is done and provides nothing new.
