For the first question I would say that the rules could be a little bit clearer about the kind of projects that are eligible (should they build on tron and bttc blockchain, mainnet/testnet, or is it enough if they promote the ecosystem without necessarily build an on-chain product).
But beside that the organisation was great. Thanks again to the whole organisation team. Thanks to @TronLive as well for keeping us entertained with your questions and for answering people’s concerns. Would be nice for the S3 if you start asking questions to the participants again as you did in S1 
For the second one, motivating a community to vote with motivational speeches and buying votes are different things. I personally think that buying votes shouldn’t be accepted. Rules should clearly state the potential sanctions if that occurs during the next hackathon. If nothing happens, it will be considered as tolerated. Which means that the community vote will lose its purpose. It will just be a freebies hunt. So I don’t see the point in being active in the forum and mobilising the community if eventually the ones who buy votes win.
