Algo for RT tweets in @GivAlertEU
This is a an abstract description of the loopback algorythm that @govalerteu uses to RT tweets from a selection of accounts.
The database keeps a list of all the accounts that are monitored with the timestamp of the last RT and check (run of this algo), the number of all tweets that were RT and the sum of their RT and fav.
For each account on regular intervals:
1. List all the tweets since the last check
2. Exclude all that are newer than 2 hours
3. Exclude all the answers
4. Sort them in 3 categories - tweets in Bulgarian, tweets mentioning Bulgaria and others. Sort these categories by the number of RTs and then by the number of fav.
5. Get the one on the top and check if it has more fav+RT than 2/3 of the average of those RT-ed until now for this account, but not less than 3. If the account hasn't been retweeted for over 4 days and 2 hours, RT the top tweet if it has more than 3 RT+fav.
