For my magazine I would have to make sure I am fully aware of the content involved inside the website through not using vulgar language or any offensive content towards any race or ethnicity eg, no white models, the use of swearing and the use of inappropriate jokes etc. This will allow the website to not get in any trouble or bother and also sell more products to a wider audience.
