@mossy It's an exceedingly unlikely scenario, yes. Generally not really a DoS attack as much as "we have a terribly performing app that somehow shows up on ask.com when people search for 'Britney Spears Boobs'". I could see doing a rule like that for blocking a very specific pattern of traffic.
I need to modify a driver to replace random four letter words starting with specific letters with other specific four letter words starting with a specific letter. And only effect certain IP addresses or usernames
random four letter words ? this reminds me of a batman word filter for a twitter ticker i made. replaced cussing with "bam!" "pow!". prolly my all time favourite bit of code.
might be overkill though. on a print driver ? - i only did it for the twitter feed cos the top bosses didnt like the large screen tv's full of swearing.
