Most NORMAL people don't want to remember usernames and passwords, so they'll use the same username and password for everything. If you get one, 50/50 odd's you'll get em all. Even if you don't, the pattern is what is important. What are the most common patterns you have seen in your time?
Here is what I've seen
<code word><1 number>
<code word><3 numbers>
<two words><1 numbers>
<two words><3 numbers>
<codeword><year born>
first letter capital, trailing "1-" is probably the most common i see for sites that force capital, number, and special character
even normies know to repeat their usual password twice now though

laziness. If I'm lazy with my files, I just might be lazy with my passwords ;)
