The same is going on with Terra (also an IBC chain) and all the drops coming out as new projects pump. I also like the idea of weekly drops as a way to keep you linked to the project, in this case, staking LUNA, the native token.
There's this other project https://giv.giveth.io/ running in the Gnosis chain (formerly xDai) which has approached the airdrop in a very nice different way. They have split the airdrop in GIV tokens and GIVStream which is a fixed amount of tokens you receive weekly for 5 years. First, you avoid treasure hunters only wanting to cash out, and second, just to claim you need to keep in touch with the project during that period of time.
Thanks for the tip, appreciate it!
