- The entry is only valid for the lottery it is entered in. That is, the pool of entrants is emptied at the end of each lottery
- Yes
- No, you would not
- Yes you can! A post can be entered as many times as you want, in as many lotteries as you want. However, keep in mind that if a post wins an upvote from @lottobot, it will not be able to be upvoted by @lottobot again, even if you enter a previously-winning post into another lottery and it wins again. This is because Steemit doesn't allow an account to upvote a single post more than once (i.e, beyond 100%)
Thanks for your interest in @lottobot :)
