UPDATE : 2018 29 January
If SafeKeet did not write 5 or more tweets in a week and you can't retweet 5 tweets from us, you can write self tweets that will count as retweets.
For example : You write 2 self tweets. SafeKeet wrote 2 tweets this week, you retweeted the 2. There is only 3 retweets and your twitter bounty week is completed. But if SafeKeet don't tweet anymore this week, you can still write 3 self tweets to match the count.
