What a cheek to hijack your twitter and then make out you're losing weight and advertising a product

Groups like that should be stopped. It's a shame that stopping things like that is hard to do.
Recently I'm fed up of seeing people on sites, comments and forums being rude for no reason, starting fights or making pointless comments that do nothing for the discussion. The worst though are liars; people who create false lives or tragedy to get sympathy. But in the end, they are usually found out. The weird thing is, sometimes these liars then get angry at the people who uncovered their deception. :/ It's also sad in a way because with internet liars being common, it is hard to tell who is being honest and really needs sympathy or kind words.
