It's PW Rule 15
15: Members posting comments should not use incomprehensible or gibberish style to type, or use formatting such as fonts and/or color excessively. It is quite annoying and very inconsiderate. Violation may result in losing your privilege to post at PakWheels.
Without adequate punctuation, paragraphing etc, Urdu is very hard to read in English. I know this is not English or Urdu class, but members should be considerate enough to make it easy to read and easily understandable for other members as well. It's an international forum after all.
In my posts, even if i come across a spelling, punctuation error, or a grammatical mistake etc, i correct it even if the post is few years old, just to make it easier for future readers and make it easily searchable.
