FYI:
IOU.BOO is the token of lottery issued by BTSABC.
https://bit.btsabc.org

The mechanism of IOU.BOO is as following:
Purchase 1 IOU.BOO each time, the price is 5 bitCNY, then you will get a transaction ID, and this TX ID is your lottery number. You may purchase multiple times to get different Tx IDs to get more lotteries.
The transaction ID a 40 digits blockhash. The last blockhash of each lottery period(1month ) is taken as the winning number. All the lottery numbers from buyers will be compared with the winning number backwards digit by digit. The closest lottery number will be the winner. A more detailed introduction can be found here:

Who is "love5"?
We have noticed that a ID named "love5" is consistently buying in the lottery issued by BTSABC, according to https://btsbots.com/u/love5
"love5" has spent over 20,000 bitCNY for more than 4000 IOU.BOO with price of 5bitCNY/IOU.BOO, and is continuing buying in.
It seems that love5 is buying in using a bot, but we are not sure what is his purpose, because according to the rules, even love5 wins the first prize, he can not profit. We are afraid that he misunderstand the rules.
We'll keep eyes on this, and hope "love5" knows what he is doing.
