The forums are full of know-it-alls who spend their entire day reading a dictionary just to own someone who spends their time learning common sense and working. Just look at the number of know-it-alls who had to keep debating about fall in the other thread.
Deleting old content obviously gives them more memory to make new content. This is basic common sense and basic computer science but the people in this forums will come up with all sorts of dictionary definition to tell you this is not how memory works or something probably because they're looking at the wrong definition of "memory", which is about human memory. But these people just want to win a debate more than they want to learn. So you have them stalking and harassing and spamming me with definitions from the dictionary.
