Is this REALLY the best copywriters can do?

One of the current CPF banner advertisement reads:

"IF YOU HAVEN'T TAKEN A PEAK AT US RECENTLY THEN YOUR MISSING SOME COOL STUFF"

Unless I'm unwittingly missing some subtle homophonic play on words here, this is a sad commentary on the pitiful standards of English within our younger generations.

The pronoun in question here is a form of the possessive case of "you", and used incorrectly in this case as an attributive adjective, rather than the correct contraction the writer was, obviously unsuccessfully, seeking.

We also find, with embarrassing regularity, "should of" et al, when in fact the writer means should have or should've. There's a thousand other lamentable examples too.

Or am I simply suffering from a bad case of pedantry?

— Cheers, Jack.

I agree with you that its terrible, but lets leave homophobia and pedophilia out of this.

BTW, "There's a thousand other lamentable examples too." should be "There are a thousand other lamentable examples, too."
