The qualification for me messaging a girl on a dating website is as follows.

I have signals that will alert me to the fact I will not like a certain girl. These signals are found in the profiles. If they have any of these they will not get a message from me.

Saying you want a real man.
Listing hardly anything about yourself(You can't take 5 minutes to list your favorite movies?).
Talkin lik dis 4 real yo
Having overtly sexual pictures(Like showing a picture of your ass, be modest).
Being skinny(Not bad, but I'm not even going to try)
Acting like a thug.
Wanting to hook up.
Noting giving me a hook so I can message you back(Why should I care if you don't sound interested?).
Living too far from me.
Insulting me because I read Shakespeare in modern English.
Living in Canada.
Being dwarf in wheel chair.

More to come when I think of it.
