I THOUROUGHLY ENDORSE THIS PRODUCT OR CERVIX.
[Words ending with -ix are excellent.]
I agree with idiomatic use of English (Fucktard; Wankbaskets etc.)
I don't mind some grammatical errors (periods; correct use of semi-colons & hyphens).
I piss blood at their/there/they're and your/you're.
I suspect that the main offenders are native speakers rather than second-languagers.
There is rarely any need for an exclamation mark. There is never a need for more than one or exclamations interspersed with question marks.
A QUESTION MARK INDICATES THAT YOU ARE WRITING A QUESTION. IF YOU DO NOT WRITE THIS I WILL READ WHAT YOU HAVE WRITTEN FIVE TIMES TRYING TO FIGURE OUT WHAT THE HELL YOU ARE SAYING. FOLLOWING THIS I WILL BE ANGRY AND CEASE TO READ YOUR POSTS.
Ellipses are a privilege, not a necessity (I am an offender here).
