What is D347H PR0N3 used for?
I sometimes use the variation D347H PR0N3
It's just an alternative spelling of Death Prone and the sort of thing I commonly use when gaming, creating logos or accounts for things.
A lot of people find that sort of thing annoying, but I've always quite liked it. Writing things like that is always handy for user names and passwords, for instance if you want PENCILS, then by using P3NC1L5 it's much harder to guess! The same with user names DEAN THORPE might be taken, but D34N 7H0RP3 might not be!
Before everybody tries logging into my Facebook, eBay or whatever using things like D347H PR0N3 that is a technique I recommend to many, but NOT one I ever use myself, I much prefer 16 digit (low importance stuff) to 32 digit (high importance stuff) completely computer random generated numbers, which are MUCH more secure, but can be a little harder to remember! lol
