We are not responsible for the individual competitions listed on this site. Each competition will have it's own terms and conditions as defined by the company or group running the competition, it is your responsibility to find the rules for the competition and make sure you are eligible and have followed the correct instructions enter the competition in a valid fashion.
Tweets will only get updated when you re-fetch them. This helps you because competitions will no longer "jump" between pages when competitions get added or competitions finish while you are browsing them. Competitions get "fetched" when you login or manually re-fetch them with "Forget Ended Competitions & Fetch New Ones". Additionally hidden tweets will stay visible until you "fetch" to save reloading the page and save you from losing your position.
