Ranking Rules
This ranking monitors tweets from the entire world that include one of these hashtags: #ff, #followfriday, #cuate, #sigueelviernes, #vivaviernes, #shoutout. We count all tweets sent between Thursday 12:00 GMT and Saturday 12:00 GMT. The #followfriday tradition makes recommendations on Fridays but we needed to extend the period to part of Thursday and Saturday in order to monitor all the countries.
Sample #followfriday tweet:

#followfriday for the e24apps.com founders @aartiles24 @javierburon @luispablopardo
The aim of the following rules is to maintain the purity of the Followfriday Ranking and ensure that the ranking is free of manipulation and is a true reflection of those valuable recommendations made.
Here you have a list of rules that guarantee the ranking quality:
- * Each followfriday tweet is worth a base score in the range of 0 to 150 points. This score is cumputed by an algorithm that semantically analyzes the tweet and measures the recommendation quality.
- * Each followfriday recommendation is worth the computed base score divided by the number of users recommended in that tweet. So if you receive a followfriday recommendation which only mentions you in the tweet, and correctly justifies why I should follow you, then you will get 150 points. If the tweet mentions 2 users you will each receive 75 points, and so on.
- If you recommend the same person repeatedly during the same week, only the first recommendation will be taken into account.
- Users that make more than 50 recommendations won't be ranked. Their profile will still be shown but they will not be ranked.
- Protected accounts won't be ranked. Their profile will still be shown but they will not be ranked.
- Self recommendations won't be taken into account.
- Retweets won't be taken into account
- Thank you tweets won't be taken into account
- If you have a lot of accounts collaborating and recommending each other to promote their rankings then all of them will be banned.
- Country and language rankings are computed based on our automatic geolocalization algorithms, if you want to be sure to appear in the correct rankings then login and edit your profile.
All of these rules are applied automatically, but we also have an anti-spam team that continually checks the rankings.
