Facebook CEO Mark Zuckerberg announced last week that the social network would begin voluntarily requiring disclaimers on political ads that appear on the site. But in 2011 Facebook went to federal regulators to get an exception from a rule that would have forced it to do the same thing.
Federal election regulations state that political "communications placed for a fee on another person's website" must carry disclaimers stating that they are advertisements and who paid for them.
Facebook (FB, Tech30) sought an exception to disclaimer regulations citing space constraints for its "character-limited ads." Lawyers for the company argued the ads were so small that a disclaimer would be impracticable, according to Federal Election Commission records reviewed by CNN.
Facebook argued, at the time, that ads on the platform were restricted to 160 characters. However, ads on Facebook have since evolved into sophisticated multimedia experiences. Advertisers can choose to sponsor videos, carousels of images and slideshows. Today, not all of Facebook's advertising options are character-limited.
Facebook asked for what is known as a "small items" exception. The FEC says small campaign paraphernalia like stickers and buttons do not need to carry disclaimers stating who paid for them.

I use it to keep up with a selected group of relatives and friends, and for nothing else. I find Twitter even more useless. I'm a serious sort of guy, and don't see either venue as serious, when it comes to news and information.

They do not want any government regulations to get in the way of their unethical business practices
