I support this grant, as an accessible means of using the chain is far more likely to facilitate user growth on Arbitrum than handing the same 100,000 ARB to a large project.
My concern however, which is not covered by the proposal, is that some means of Sybil resistance will be required to prevent gaming of the incentive system. How do you propose to prevent the incentive being drained by a person creating many accounts? Will the app require linking to a mobile phone number (better than nothing, but still heavily game-able as they are available in bulk for verifications at less than 10 ARB each) or perhaps KYC (which to many potential users carries its own privacy and identity theft concerns)?
