Whenever a forum thread you've created goes to the dogs, the least painful of solutions is to simply "Do a Dairy."
To attempt this cunning tactic all you need is to up the font size of your post and scream "MODS PLEASE DELETE!" in the vain hope that one of those good for nothing lazy buggers actually pay attention to your pleas as opposed to scoffing at you arrogantly before turning you down.
It's worth a shot.
The technique was first un-successfully attempted by DairyDark Lynx who tactic has since become known as the aforementioned "Doing a Dairy".
"OMG, everyone's laughing at my new thread!!11"
"Do a Dairy man."
"MODS PLEASE DELETE!!"
"Oh gahd, he's really doing a dairy!"
