Re: off-topic: You have to do it fast. You certainly can tweet a lot of identical tweets if you aren't in a hurry: there is a "Rock in the forest"[1] that tweets "Nothing happened today" (in Russian) every day for several years, and most of the time the text is exactly the same. Interestingly enough, the time of tweet varies widely from day to day, so it looks like a human or a program specifically made to imitate one.
