On many news sites that have a comment section(what I meant by News Forums), they commonly delete messages that they do not agree with. Even though its not making personal attacks. Which doesn't make any sense since the news sites have freaking ads on them. People spending longer on the website voicing their opinion are going to be exposed to more ads and its going to help increase revenue for the news sites. Is it usually done on purpose, or the moderators just don't have the interest of corporate on their mind when they are moderating.
