Right now we seem to get most of our followers from manually searching for tweets related to our account and favoriting them, it is a grueling process but it is what brings in the majority of our followers. There is a maximum amount you can favorite though per day, I've read it's 1000 but not sure if that is true or not. It seems to go away after doing a bunch in the morning and then allows us to do more later in the day before not letting you again. Can anyone explain how exactly it works? It would be great to know. Thanks.
