That was just an example of the marketing strategy, an inspiration for other projects that wish to promote Nostr in specific communities like college campuses.

I think they are not an example to follow tbh. I don't think this marketing bribery strategy would work outside of Bitcoinery circles, I'm not even sure it works all that well inside these circles either. And worst case scenario is it actually works and cements nostr as being an irrelevant bitcointwitter2 silo
